Question

find the area of a rhombus in which each side is 15 cm long and one of whose diagonal is 24 cm

Answer 1

I hope this will help you.

Answer 2

By Pythagoras theorem,

(24/2)² + (half of other diagonal)²=15²

12²+(half of other diagonal)²=225

(Half of other diagonal)²=225-144=81

Half of other diagonal =√81=9

Other diagonal =2*9=18cm

Area =product of diagonals/2

Area =24*18/2

Area =12*18

Area of rhombus =216cm²
