Question

] In the adjoining figure A (APQS) = 100. A (AQRS) = 150 cm2 PM = 10 cm.
Complete the following activity to find NR. A PQS and A QPS have same base QS.
Triangles having same base have areas propotional to their corresponding.
A (APQS)
A (AQRS)
NR.
100
150
NR
NR =
cm.
.​

Answer 1

Answer:

11 cm

From△PQS&△QRS, the have the same base.

∴

ar(△QRS)

ar(△PQS)

=

NR

PM

Triangles with same base have areas are proportional heights.

∴

110

100

=

NR

10

⟹NR=

100

110×10

=11cm.
