Question

The perimeter of a Rhombus is 40 cm then the length of its side is…………cm. 

A) 10 

B) 16 

C) 32 

D) 70

Answer 1

Correct option is (A) 10

All 4 sides are equal in a Rhombus.

Let one side is of length a unit in Rhombus.

\(\therefore\) Perimeter of Rhombus = Sum of all 4 sides

= 4a

\(\Rightarrow\) 4a = 40 cm  \((\because\) Perimeter = 40 cm (given))

\(\Rightarrow\) \(a=\frac{40}4\,cm\) = 10 cm

Answer 2

Correct option is  A) 10
