:
Let x = length of the side of the smaller square:
Perimeter = 4x
and
(x+5) = length of the side of the larger square
Perimeter = 4(x+5)
:
The total perimeter of the two squares = 36 in, solve for x:
4x + 4(x+5) = 36
4x + 4x + 20 = 36
8x = 36 - 20
8x = 16
x = 16/8
x = 2" length of the smaller square
and
2 + 5 = 7" length of the larger square
:
Sum of the Areas:
2^2 + 7^2 =
4 + 49 = 53 sq/inches
