Question

Find the area of a rhombus whose diagonals are of lengths 20 cm and 16cm

Answer 1

area of rhombus= 1/2*d1* d2
= 1/2*20*16
=160cm

Answer 2

It's very easy first u know that diagonals of a rhombus bisect at 90degree so the diognals form 4 congruent triangles so by Pythagorean theorem u can find one side which is 10^10+8^8= one side in the same way find the other sides and by using the formula of area of rhombus we can find the area of rhombus
