Question

Find the area of the irregular figure . ( Assume that all angles are right angles )

a) 10 in 2


b) 11 in 2

c) 13 in 2

d) 15 in 2

Answer 1

if you multiplied 2x3 you get the area of half of the whole figure. But to get the other portion I subtracted 4-3 and got 1, the I multiplied 5x1 and got 5. so the answer is 11in^2.

Answer 2

Explanation:

From the given figure, divide the proportion in such a way that we have two rectangles, then Area of one rectangle=
`l{*}b=2{*}3=6 sq inches`

and area of the another triangle=
`l{*}b=5{*}1=5 sq units`

Therefore, Area of the irregular figure= Area of rectangle 1 + arae of rectangle 2

=
`6+5=11 sq inches`

Thus, area of the irregular figure= 11 sq inches.
