Question

Calculate the area of quadrilateral PQRS when
length of diagonal PR = 10 cm and length of
perpendiculars from Q and S on PR be 5 cm and
6 cm respectively.​

Answer 1

Answer:

55cm^2

Step-by-step explanation:

Ar.∆PQR=1/2×PR×5=50/2=25CM^2

Similarly,

Ar.∆PRS=1/2×PR×6=60/2=30cm^2

Total Area=25+30=55cm^2
