Question

Find the area of shaded portion.



The formula for trapezium is given below
$\frac{1}{2} \times 100(120 + 160)$


​

Answer 1

Answer:

13046 Sq. cm

Step-by-step explanation:

Total area of the trapezium = 1/2 × 100(120+160) = 1/2 × 100 × 280 = 14000

To find the area of the shaded portion we will just just subtract the area of the unshaded rectangle and circle from that of the trapezium

Area of the rectangle = 20 × 40 = 800

Area of the circle = pi × r^2 = 22/7 × 7 × 7 = 154

Area of the shaded portion = 14000 - 800 - 154 = 13046 Sq. cm
