Answer:
Option B
Explanation:
The area of the two triangles in the tent is 2(B) = 2(1/2*6*4) = 2*12 = 24 cm^2
There are 3 rectangles left in the figure, two of which have the dimensions 5 by 9: 5*9 = 45, 45(2) = 90 cm^2
The other rectangle has the dimensions 6 by 9: 6*9 = 54 cm^2
S = 24+90+54 = 168 cm^2
