Let x = side of the square
x+10 = length of the rectangle
x-8 = width of the rectangle

Area of Square = Area of Rectangle
x%5E2+=+%28x%2B10%29%28x-8%29+
x%5E2+=+x%5E2+%2B+2x+-+80

Subtract x%5E2 from each side.

0=+2x+-+80+
80=2x
x=40 meters

Check:
Area of square = x%5E2+=+40%5E2+=+1600+m%5E2
Area of rectangle = %28x%2B10%29%2A%28x-8%29+=+50%2A32+=+1600+m%5E2
