Question

The squares are identical. What is the area of each square?

Answer 1

Answer:

A = 256 units^2

Step-by-step explanation:

If the squares are identical, then the side lengths are identical

3x+7 = 5x+1

Subtract 3x from each side

3x+7-3x = 5x-3x+1

7 = 2x+1

Subtract 1

7-1 =2x+1-1

6 = 2x

Divide by 2

6/2 =2x/2

3 =x

The side length is 3x+7 = 3*3 +7 = 9+7 = 16

The area is

A = s^2 where s is the side length

A = 16^2

A = 256 units^2
