To find the perimeter of a rectangle, we will use the following formula:

\(\displaystyle P = a+b+c+d\)

Where a, b, c, and d are the lengths of the sides of the rectangle.

Now, we know the length of the rectangle is 36cm.  Because it is a rectangle, the opposite side is also 36cm.  We also know the width is a third of the length.  Therefore, the width is 12cm.  Because it is a rectangle, the opposite side is also 12cm.

Knowing this, we can substitute into the formula.  We get

\(\displaystyle P = 36\text{cm} + 36\text{cm} +12\text{cm} + 12\text{cm}\)

\(\displaystyle P = 96\text{cm}\)

To find the perimeter of a rectangle, we will use the following formula:

\(\displaystyle P = a+b+c+d\)

Where a, b, c, and d are the lengths of the sides of the rectangle.

Now, we know the width of the rectangle is 6in.  Because it is a rectangle, the opposite side is also 6in.

We know the length is four times the width.  Therefore, the length is 24in.  Because it is a rectangle, the opposite side is also 24in.

Knowing this, we can substitute into the formula.  We get

\(\displaystyle P = 6\text{in} + 6\text{in} + 24\text{in} + 24\text{in}\)

\(\displaystyle P = 60\text{in}\)

To find the perimeter of a rectangle, we will use the following formula:

\(\displaystyle P = a+b+c+d\)

Where a, b, c, and d are the lengths of the sides of the rectangle.

Now, we know the width of the rectangle is 2cm.  Because it is a rectangle, the opposite side is also 2cm.

We know the length is six times the width.  Therefore, the length is 12cm.  Because it is a rectangle, the opposite side is also 12cm.

Knowing this, we can substitute into the formula.  We get

\(\displaystyle P = 2\text{cm} + 2\text{cm} + 12\text{cm} + 12\text{cm}\)

\(\displaystyle P = 28\text{cm}\)

To find the perimeter of a rectangle, we will use the following formula:

\(\displaystyle P = a+b+c+d\)

Where a, b, c, and d are the lengths of the sides of the rectangle.

Now, given the rectangle,

we can see the length is 9cm.  Because it is a rectangle, the opposite side is also 9cm.

We can see the width is 7cm.  Because it is a rectangle, the opposite side is also 7cm.

Knowing this, we can substitute into the formula.  We get

\(\displaystyle P = 9\text{cm} +9\text{cm} + 7\text{cm} + 7\text{cm}\)

\(\displaystyle P = 32\text{cm}\)

To find the perimeter of a rectangle, we will use the following formula:

\(\displaystyle P = a+b+c+d\)

Where a, b, c, and d are the lengths of the sides of the rectangle.

Now, we know the width of the rectangle is 6in.  Because it is a rectangle, the opposite side is also 6in.

We know the length is three times the width.  Therefore, the length is 18in.  Because it is a rectangle, the opposite side is also 18in.

So, we can substitute.  We get

\(\displaystyle P = 6\text{in} + 6\text{in} + 18\text{in} + 18\text{in}\)

\(\displaystyle P = 48\text{in}\)

To find the perimeter of a rectangle, we will use the following formula:

\(\displaystyle P = a+b+c+d\)

Where a, b, c, and d are the lengths of the sides of the rectangle.

Now, we know the width of the rectangle is 4cm.  Because it is a rectangle, the opposite side is also 4cm. 

We know the length is three times the width.  Therefore, the length is 12cm.  Because it is a rectangle, the opposite side is also 12cm.  

So, we can substitute. 

\(\displaystyle P = 4\text{cm} + 4\text{cm} + 12\text{cm} + 12\text{cm}\)

\(\displaystyle P = 32\text{cm}\)

To find the perimeter of a rectangle, we will use the following formula:

\(\displaystyle P = a+b+c+d\)

Where a, b, c, and d are the lengths of the sides of the rectangle.

Now, we know the width of the rectangle is 6in.  Because it is a rectangle, the opposite side is also 6in.  

We know the length is two times the width.  Therefore, the length is 12in.  Because it is a rectangle, the opposite side is also 12in. 

So, we get

\(\displaystyle P = 6\text{in} + 6\text{in} + 12\text{in} + 12\text{in}\)

\(\displaystyle P = 36\text{in}\)

To find the perimeter of a rectangle, we will use the following formula:

\(\displaystyle P = a+b+c+d\)

Where a, b, c, and d are the lengths of the sides of the rectangle.

Now, we know the length of the rectangle is 16cm.  Because it is a rectangle, the opposite side is also 16cm.  We also know the width of the rectangle is a quarter of the length.  To find the width, we will divide 16 by 4.  Therefore, the width is 4cm.  Because it is a rectangle, the opposite side is also 4cm.

Knowing this, we can substitute into the formula.  We get

\(\displaystyle P = 16\text{cm} + 16\text{cm} + 4\text{cm} + 4\text{cm}\)

\(\displaystyle P = 40\text{cm}\)

This problem requires finding the height of the rectangle first.

Write the formula for the area of the rectangle, and substitute the known values.

\(\displaystyle A=bh\)

\(\displaystyle 50=2h\)

Divide by two on both sides to obtain the height.

\(\displaystyle \frac{50}{2}=\frac{2h}{2}\)

\(\displaystyle h=25\)

The perimeter of a rectangle includes 2 bases and 2 heights.

The formula for the perimeter is:

\(\displaystyle P=2b+2h\)

Substitute the values to find the perimeter.

\(\displaystyle P=2(2)+2(25) = 4+50 = 54\)

The perimeter is:  \(\displaystyle 54\)
