Question

9. Find the length of the diagonals of a rectangle whose sides are 24 cm and
10 cm.

Answer 1

Answer:

26 is the correct answer.

Answer 2

Answer :

Diagonal of the rectangle is 26 cm long.

$\rule{100}2$

We know that each angle of rectangle is 90°.

Also,

• Perpendicular = 24 cm
• Base = 10 cm

By using pythagoras theorem :

H² = P² + B²

⇒ H² =  ( 24 )² + ( 10 )²

⇒ H² = 576 + 100

⇒ H² = 676

⇒ H = √676

∴ H = 26 cm

Answer : Diagonal of the rectangle is 26 cm long.
