Answer:

226 11/20 cm^2.

Explanation:

This consists of 2 trapezoids and 4 rectangles.

Area of the 2 trapezoids = 2 * 4 *(6 1/2 + 5 1/4 ) /2

= 47 cm^2.

Area of the 4 rectangles = 4*9 + 6 1/2 * 9 + 4 1/5 * 9 + 9* 5 1/4

= 36 + 117/2 + 189/5 + 189/4

= 3591/20 cm^2

Total surface area = 47 + 3591/20

= 4531/20

= 226 11/20 cm^2.
