Example Question #1291 : Ged Math
What is the perimeter of a square with a side length of 
The square has four congruent sides.
Multiply the side length by four.
The answer is:
Example Question #1292 : Ged Math
What is the perimeter of a square if the side length is 
A square has four congruent sides.
Multiply the quantity by four.
The answer is:
Example Question #33 : Squares, Rectangles, And Parallelograms
The above rectangle has area one square foot. Give its height.
One square foot is equal to 144 square inches. The area of a rectangle is equal to its length times its height:
Set 
Divide both sides by 16 to solve for 
The height of the rectangle is 9 inches.
Example Question #34 : Squares, Rectangles, And Parallelograms
The ratio of the length of a rectangle to its width is 6 to 5. The perimeter of the rectangle is 99. Give its length.
The ratio of the length of a rectangle to its width is 6 to 5, so if we let 
Multiply both sides by 
The perimeter of the rectangle is equal to
Set this equal to 99 and set 
Simplify:
Collect like terms by adding coefficients:
Reduce:
Multiply both sides by 
the correct length.
Example Question #1293 : Ged Math
Your mother made a casserole in a pan whose length is 9 inches and whose width is one and a half times the length. What is the perimeter of the casserole pan?
Not enough information to solve.
Your mother made a casserole in a pan whose length is 9 inches and whose width is one and a half times the length. What is the perimeter of the casserole pan?
To find the perimeter, you need to add up all the side lengths. First, however, we need to find our width.
We can find our width by using the clue: "...one and a half times the length"
So, do the following:
Next, let's find our perimeter:
So, our answer is 45 in
Example Question #36 : Squares, Rectangles, And Parallelograms
Square 1 has area 64; Square 2 has perimeter 24.
Give the ratio of the length of a side of Square 1 to the length of a side of Square 2.
The length of a side of a square is equal to the square root of its area. Square 1 has area 64, so each side has length 
The length of a side of a square is one fourth its perimeter. Square 2 has perimeter 24, so each side has length 
The ratio of the sidelengths is 
Example Question #331 : 2 Dimensional Geometry
A square and a right triangle share a side as shown by the figure below.
Find the area of the square.
Notice that the side of the square is the same as the hypotenuse of the right triangle.
Use Pythagorean's theorem to find the length of the hypotenuse.
Now that we have the length of a side of the square, find the area.
Example Question #42 : Perimeter And Sides Of Quadrilaterals
Find the perimeter of trapezoid 
Since we know that 
Using that value,
Thus, we can find the perimeter of the trapezoid.
Example Question #332 : 2 Dimensional Geometry
What is the perimeter of a square that has an area of 
First we need to recognize that in order to find perimeter we first need to figure out the length of each side of the square. The formula for area of a square is
where 
To solve for 
Now that we know our side length is 13, we can plug it into our perimeter equation and solve for s
We multiply 4 and 13
Notice our answer is in ft because perimeters are linear
Example Question #1294 : Ged Math
Find the area of the trapezoid:
The area of a trapezoid is calculated using the following equation:
