Find the perimeter of a rectangle with a length of 7cm and a width that is half the length.
The formula to find the perimeter of a rectangle is
where a, b, c and d are the sides of the rectangle. We know the length is 7cm and the width is half the length. So, the width is 3.5cm. So, we can substitute and get
Note that when we add, we do not combine the labels, we only combine the numbers.
Example Question #37 : Perimeter Of A Rectangle Or Square
What is the perimeter of a rectangle with width of 4 meters and length that is triple its width?
What is the perimeter of a rectangle with width of 4 meters and length that is triple its width?
First, let's find the dimensions of our rectangle.
Width is easy, it is given to us as 4 meters.
Length is a little trickier, it is triple the width:
Next, we need to recognize that perimeter is the distance around the outside of our shape.
Because we have a rectangle, we know that we have two 12 meter sides and two 4 meter sides.
So we do the following to get our answer:
