Question

FInd the area of quadrilateral PQRS
PX=3.2cm
QS=10.5 cm
RY=4.8cm​

Answer 1

Answer:

area of the quadrilateral is 42 cm²

Step-by-step explanation:

In triangle ∆ PQS:

Base = QS = 10.5 cm

Height = PX = 3.2 cm

area of the triangle = 1/2 × B × H

= 1/2 × 10.5 × 3.2

= 10.5 × 1.6 = 16.8 cm²

In triangle ∆ RQS:

Base= QS = 10.5 cm

height = RY = 4.8 cm

area of the triangle= 1/2 × B × H

= 1/2 × 10.5 × 4.8

= 10.5 × 2.4

= 25.2 cm²

area of the quadrilateral= 16.8 + 25.2= 42 cm²
