Question

Find the x and find the A.

Answer 1

x=13, A=169

P=4s, so you substitute P with 52 and you're left with 52=4a. You divide 4 to both sides of the equation and a(or x) equals 13.

A=s^2, so since your side(x) equals 13 you calculate 13^2 or 13×13, and A=169.

Answer 2

13 = x

169 in^2 = A

Explanation:

Since perimeter is given as 52 in we can find x by dividing 52 by 4 because the area is calculated by adding all side lengths together

52 ÷ 4 = x

13 = x

The area is calculated by multiplying height to the base , the height given here is 13 and since this is a cube it has all side lengths in equal measure therefore the area for thid shape is

13 × 13 = 169 in^2
