Question

find the length of one of the diagonals of a rectangle having sides of length 10 cm and 24 cm respectively

Answer 1

We Know, All sides of rectangle are perpendicular to each other,





By Pythagoras theorem,



Length² + breadth² = diagonal²

( 10 )² + ( 24 )² = diagonal²

=> 100 + 576 = diagonal²

=> √ 676 = diagonal

=> 26 = diagonal




Length of diagonal= 26 cm



$.$

Answer 2

Using Pythagoras' theorem:

a² + b² = c²

Find Diagonal:

10² + 24² = c²

c² = 676

c = √676

c = 26

Answer: 26 cm
