Answer:
x = 19m
Explanation:
to find the other two sides of the compound shape,
(2+6+6)= 14m , and (x-2)m
area of the compound shape = (2 x 14) + 2(x-2) =28 + 2x - 2 = 2x+26 m²
area of square = 8 x 8 = 64 m²
the question states that these two shapes have the same area,
2x + 26 = 64
2x = 38
x = 38/2
x= 19m
