Question

Devin drew a rectangle that is 4 inches by 9 inches. It has an area of 36 square inches and a perimeter of 26 inches.

Answer 1

The answer is 2 inches by 11 inches because 11+11+2+2=24 and 11*2 is equal to 22. Hope this helped! :)

Answer 2

The perimeter is given by the following formula:

$P = 2l + 2w$

l is the length, and w is the width of the rectangle.

We know that the perimeter is 26, so plug it into the formula:

$26 = 2l + 2w$

Divide both sides by 2:

$13 = l + w$

Take any two numbers that add up to 13:

$13 = 3 + 10$

3 and 10 can add up to 13.

The area of a rectangle is given by the following formula:

$A = lw$

Plug in your length and width for this equation:

$A = 3 \times 10 = 30$

The area of this rectangle is 30 square inches.

A rectangle that is 3 inches by 10 inches gives the same perimeter, but a different area.
