Question

The length of the diagonals a rhombus are 24cm and 18cm. Find the perimeter and area of the 

rhombus.

Answer 1

 

The length of the diagonals a rhombus are 24cm and 18cm.

Calculate the area of the rhombus by using formula : A = (1/2) * d₁ * d₂, where d₁ and d₂ are diagonals of the rhombus.

Substitute the values of d₁ = 24 and d₂ = 18 in the above formula.

A = (1/2) * (24) * (18) = 216 cm².

Calculate the perimeter of the rhombus by using formula : P = 2√[(d₁)² + (d₂)²], where d₁ and d₂ are diagonals of the rhombus.

Substitute the values of d₁ = 24 and d₂ = 18 in the above formula.

P = 2√[(24)² + (18)²] = 2√(576 + 324) = 2√(900) = 2(30) = 60 cm.
