KEY:
LENGTH=L
WIDTH=W
AREA=A
If the length of 1 side is 8 and the area is 24, we must find the other length. Since L*W=A we know that L=8 and A=24. So, the problem looks like this: 8*W=24. So, to reverse this, 24 divided by 8 = W. 24 divided by 8 = 3, so we know that L=8 and W=3. Perimeter = W+W+L+L so 8+8+3+3= 22. I hope that you understand the process. Please post something on my page if you need further help.
28 inches
the area of a rectangleis 100 square inches. The perimeter of the rectangle is 40 inches. A second rectangle has the same area but a different perimeter. Is the secind rectangle a square? Explain why or why not.
yes
That is not a square, it is a rectangle and it has a perimeter of 36 inches.
The area of a rectangle is 56.25 square inches. The length of the rectangle is12.5 inches what is the width
28 inches
Perimeter = 24 inches Area = 35 square inches
Perimeter = 32 inches. Area = 55 square inches.

yes
Perimeter of a rectangle = 2 x (length + width) = 2 x (2 + 9) = 2 x 11 = 22 square inches.
That is not a square, it is a rectangle and it has a perimeter of 36 inches.
If that's a rectangle, the perimeter is 24 inches and the area is 27 square inches.
The perimeter of any rectangle is [ 2 x (length + width) ]. Since the length and width of a square are equal, the perimeter of a square is also [ 2 x (side + side) ] = (4 x side).
The area of a rectangle is 56.25 square inches. The length of the rectangle is12.5 inches what is the width
The perimeter is 35.78 inches.
You must first calculate the width, using the formula for the area of a rectangle (plug in the numbers you know into the formula, and solve for width). Once you know this, you can plug in the numbers in the formula for a rectangle's perimeter.
