Answer:
226 11/20 cm^2.
Step-by-step 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.
Answer:
40ft^2
Step-by-step explanation:
multiply :
2(2*3)
2(2*2.8)
2(3*2.8)
Each value in the parenthesis are the areas of 3 different sides. You then multiply by two because there is another side opposite to the side that is the same.
then add all of those up
you get 40
