Question

2 The area of a rhombus is 84 metre square. If its perimeter is 40 then find its altitude.​

Answer 1

Given that, Area of rhombus = 84 m2

Perimeter = 40 m

We know that,

Perimeter of rhombus = 4 × side

∴ Side of rhombus = Perimeter / 4 = 40/4 = 10

So, Side of rhombus = 10 m

Since rhombus is a parallelogram, therefore Area of parallelogram = base × altitude 84 = 10 × altitude Altitude = 84/10 = 8.4 So, Altitude of rhombus = 8.4 cm
