Find the area of the shaded portion in the following figure.
Advertisements
Solution
Area of shaded region = Area of the parallelogram ABCD – Area of ΔABE
∵ Area of a parallelogram = Side × Height
∴ Area of a parallelogram ABCD = 40 × 30 = 1200 cm2
Area of ΔAEB = `1/2 xx AB xx EF`
= `1/2 xx 40 xx 30`
= 600 cm2
∴ Area of shaded region = 1200 – 600 = 600 cm2
