Question

In the right-angled $△PQR,\angle P={90}^{\circ }.$ If $l\left(PQ\right)=24$ cm and $l\left(PR\right)=10$ cm, find the length of side $QR?$

Answer 1

Given In $△PQR,\angle P={90}^{\circ }$

$⟹Q{R}^2=P{Q}^2+P{R}^2$ ........ by Pythagoras theorem.

given $PQ=24cm,PR=10cm$

$⟹QR=\sqrt{{24}^2+{10}^2}=26cm$
