Area of composite figures 8m 8m 8m

Have to find the area of square + area of sector + area of triangle.

Area of square = 8 x 8
= 64m^2

Area of sector = 22/7 x 8^2 x 90/360
= 50.3m^2

Area of triangle = 1/2 x 8 x 8
= 32m^2

Area of composite shape = 64 + 50.3 + 32 = 146.3m^2

Answer is either b or c
