Question

pls answer this question ​

Answer 1

Answer:

a). area ∆PSR = 90-50 = 40cm^2

b). In both the triangles height will be same

so. area∆QPS : area∆ PSR =( 1/2 * QS *h) : (1/2 * SR *h)

area ∆QPS : ∆OSR = QS: SR

50 : 40 = QS : SR

5:4 = QS:SR

c). we know the ratio so

5:4= 10: SR

SR = 8 cm
