Question

Find the area of a rhombus whose diagonal are 10cm and 14cm

Answer 1

We have,

d1 = 10cm, d2 = 14 cm

So, area of rhombus =$\textbf{ 1 / 2 ( d1 x d2) }$

= 1 / 2 ( 10 x 14)

= 1 / 2 ( 140)

= 70 cm ^2

Answer 2

Given, first diagonal= d1= 10cm Second diagonal= d2= 14cm   Area of Rhombus = A= d1 x d2/2  A= (10x14/2) cm² A= (140/2) cm² A= 70 cm²  Hence, Area of Rhombus = A= 70cm²
