Answer:
Explanation:
We know that,
In a Right angled triangle: By Pythagoras theorem,
(Hypotenuse)² = (Base)²+(Perpendicular)²
As PQR is a right angled triangle with
Base = PQ = 10cm
Perpendicular = PR = 24cm
Hypotenuse = QR
So,by Pythagoras theorem
(QR)=(PQ)²+(PR)²
(QR)=(10)²+(24)²
(QR)²=100+576
(QR)²=676
QR=26cm
Hence, length od QR is 26cm Ans.
