Question

In ∆PQR, the length of side QR is 98 cm. The length of the side PQ is half of the length of the side QR. If the length of side RP is a whole number, the maximum possible length of RP is ______cm.

Pls answer correct and fast...

Answer 1

Answer:

pq = 8 cm is smallest side of triangle pqr

length of the side qr is less than twice the length of the side pq by 2 cm.

=> qr  = 2 * pq  - 2

length of the side pr exceeds the length of the side pq by 10 cm

=> pr = pq + 10

Perimeter = 40 cm

=> pq + qr + pr  = 40

=> pq + 2*pq - 2 + pq + 10 = 40

=> 4pq  = 32

=> pq  = 8

pq = 8 cm

qr = 2*8 - 2 = 14  cm

pr = 8 + 10 = 18 cm

pq = 8 cm is smallest side of triangle pqr
