Question

find the area of the polygon ABCDEF if triangleBAF
is equal to triangle CDE​

Answer 1

Answer:

area of rectangle = l x b = 50 x 30 = 1500cm2

area of each triangle = 1/2 × b × h = 1/2 x 30 x (70 - (50 + 10)) = 15 x 10 = 150cm2

area of polygon = area of rectangle + (2 x (area of triangle)) = 1500 +2(150) = 1500 + 300 = 1800cm2
