Question

PQRS is a rectangle (PQ)=5cm; (QS)=13cm, Then find Perimeter of ∆PSR
​

Answer 1

Answer:

perimeter of PSR = 30 cm

Step-by-step explanation:

IN TRIANGLE PQS , angleP =90°

PQ= 5cm , QS= 13cm

BY PYTHAGORAS THEOREM

QS²= PQ²+ PS²

13²= 5² + PS²

169 = 25 + PS²

PS² = 169 - 25

PS²= 144

PS= 12

PERIMETER of ️PQS = PQ+QS+PS

= 5+13+12

= 30 cm
