Question

find the area of shaded region ​

Answer 1

Step-by-step explanation:

area of shaded region = area of triangle PQR - area of triangle PSR

area of triangle PQR = 0.5 * base *height

= 0.5 *20*10

=100 cm2

area of triangle PSR = 0.5*base *height

=0.5*20*12

=120 cm2

area of shaded region = 120-100

=20 cm2
