Answer 1

Answer:

To calculate the area of the shaded portion you need to give the required condition in this figure:

Area of shaded portion = Area of rectangle - Area of triangle AEF - Area of triangle EBC

now caculte the areas reqired here

Area of rectangle=10 X 18 = 180 square cm

Area of triangle AEF = 1/2 X 6 X 10 = 30 square cm

Area of triangle EBC = 1/2 X 8 X 10 = 40 square cm

now put all the values,

area of shaded portion = 180-30-40 = 110 square cm
