Question

if the diagonals of a rhombus are 10cm and 8cm then find its area​

Answer 1

Given that ;

The diagonals of a rhombus are 10 cm and 8 cm.

d₁ = 10 cm

d₂ = 8 cm

We know that,

The area of rhombus is given by dividing the product of diagonals by 2.

We have -

Area of rhombus = \sf \dfrac{1}{2} * d_1 * d_2

⇒ Area of rhombus = \sf \dfrac{1}{2}*10*8

∗10∗8

⇒ Area of rhombus = \sf \dfrac{1}{2}*80

∗80

⇒ Area of rhombus = 40 cm²

Hence, the area of rhombus is 40 cm².
