Question

2. Find the area of a quadrilateral PQRS in which angle QPS = angle SQR = 90. PQ=12 cm,PS = 9 cm, QR = 8 cm and SR = 17 cm (Hint: PQRS has two parts)​

Answer 1

Answer:

In ∆PQS

PQ^2+PS^2=QS^2

QS=15cm

By applying herons formula in triangle PQS AND triangle QRS

we get,

area of PQS =54 cm^2

area of QRS = 60cm^2

area of PQRS= area of PQS +area of QRS

area of PQRS=114 cm^2
