Question

find the area of quadrilateral pqrs as shown in the adjoining figure

Answer 1

Area of quadrilateral = area of triangle PRS + area of triangle PQR

Area of quadrilateral = 24 + 48
Area of quadrilateral = 72 cm²

Answer 2

Answer:

Step-by-step explanation:

First we have to find the area of triangle PRS i.e 1/2*base*height

=1/2*12*4

=24cm

Then, we'll find the area of triangle PRQ that is also the same

=1/2*12*8

=48cm

Now the area of quadrilateral PQRS = ar of traingle PRS+ ar of triangle PRQ

i.e 24+48

=72cm
