# The area of a rhombus is 84 m2. If its perimeter is 40 m, then find its altitude.

Given: Area of rhombus = 84 m2

Perimeter = 40 m

To find: The length of altitude

Formula Used:

Perimeter of rhombus = 4 × side

Area of parallelogram = base × height

Explanation:

As Perimeter of rhombus = 4 × side

Side of rhombus

Rhombus is a type of parallelogram,

Hence area of rhombus = area of parallelogram

Base× altitude = area of parallelogram

10 × altitude = 84

Altitude of rhombus = 8.4 m
