Answer: 66.5
Explanation:
divide the figure into a triangle (the top part) and a rectangle (the lower part)
To find the area of the rectangle use the formula:
length times width = area
(LW=A)
8 times 7 is 56 so the area of the rectangle is 56.
the formula for area of a triangle is base times height halfed
(BH)1/2
the height is 3 because the height of the entire figure is 11 so subtract the height of the rectangle from that (8) to get 3.
the base is 7 so
7(3)(1/2) is 10.5
add up the two areas together (10.5+56) to get 66.5 cm squared.
answer: 66.5
