ok ... so the way i solved this is by finding the correct side measurements ... so in this there are 2 rectangles ... so lets find the area of both rectangles individually and then add it together ... so the rectangle on the top will be a and the down one will be b
rectangle a :
as we know ... a rectangle has opposite sides equal . the side on the right is 20 ... subtract it from 11 ... if we do that we get 9 ... which is the length of rectangle a and as the top is 7 bottom will be 7 too
now we know the sides of rectangle a which is 7 and 9
and area of rectangle : l × b , ∴ 7×9= 63
now b ... sides of rectangle b are 14 and 11
so 14×11= 154
now add it ... 154 + 63 = 217
∴ = 217 sq.
