Question

In the adjoining figure ABCD is a rectangle. Find the area of the shaded part.​

Answer 1

Answer:

Hello there,

73 cm^2

Step-by-step explanation:

I think your diagram is wrong.

I think your diagram is wrong.It can't be 100 cm. I think it should be 10 cm.

If we take 10cm instead of 100 cm, we get,

Area of the whole rectangle = 18 × 12

= 216 cm^2

Area of the un - shaded region = (1/2 × 12 × 10) + (1/2 × 7 × 18) + (1/2 × 5 × 8) (Reason = 5 = 12 - 7, 8 = 18 - 10)

= (60 + 63 + 20)

= 143 cm^2

Area of the shaded region = 216 - 143

= 73 cm^2

This is your answer.
