Question

PQRS is a rectangle in which PQ = 12cm and PS = 8cm. Calculate the area of ΔPRS.

Answer 1

Since PQRS is a rectangle, therefore PQ = SR.
SR = 12cm
PS = 8cm

ar(ΔPRS) = `(1)/(2) xx "base" xx "height"`

ar(ΔPRS) = `(1)/(2) xx "SR" xx "PS"`

ar(ΔPRS) = `(1)/(2) xx 12 xx 8`

ar(ΔPRS) = 48cm².
