Question

Find the area of quadrilateral PQRS shown in the figure.

Answer 1

Answer:

Answer is 19.5 cm²

Step-by-step explanation:

SOLUTION

In the given figure,

d = 6.5cm

h1 = 3.5cm

h2 = 2.5cm

Area of quadrilateral PQRS = 1/2 d(h1 + h2)

=> 1/2 × 6.5 × (3.5 + 2.5) cm²

=> 1/2 × 6.5 × 6 cm²

=> 19.5 cm²

Hence,

the area of quadrilateral is 19.5 cm².

Answer 2

Solution

Area of quadrilateral

Area= 1/2 ×8×(20+12)

=32×4=128m²
