Question

in the adjoining figure ,∆PQS is an isocles triangle with PQ=PS=5 cm,QR=3 cm .PR is an altitide .find the perimeter of ∆PQR​

Answer 1

Step-by-step explanation:

triangle PQS

we put in phythagorus theorem,

length of PR =

$5 { }^{2} =1.5 {}^{2} + x \\ 25 = 3 + x \\ x = 25 - 3\\ x = 22.75 \\ x = 4.7....$

$5 + 1.5 + 2 + 4.7 \\ perimeter = 11.2$
