Question

The lengths of diagonals of a rhombus are 24cm and 10cm the perimeter of the rhombus (in cm ) is :

A) 52 B) 56 C) 68 D) 72

Answer 1

Area = 1/2 * 24 * 10

= 120 cm^2.

Perimeter s^2 = (24/2)^2 + (10/2)^2

= 12^2 + 5^2

= 169

s = 13.

The perimeter of the rhombus = 4 * 13 = 52cm.

Therefore answer is A.
