Question

area of shaded part ?​

Answer 1

Step-by-step explanation:

Just calculate the area of the entire figure and subtract the areas of the unshaded parts from there.

Area of the square = 20×20 cm^2 = 400 cm^2

Area of ∆PQT + Area of ∆TSU + Area of ∆QRU =

(100+50+100) cm^2 = 250cm^2

So, area of the shaded part = 400-250 = 150 cm^2

Answer 2

area of square- area of 3 triangles
=20^2-1/2*10*10-2*1/2*20*10
=150 sq cm
