Question

The lenths of diagonals of a rhombus are 30cm and 40cm. Find side of rhombus

Answer 1

we know diagonals bisect each other at right angles.

each other at right angles.

30/2 = 15
40/2 = 20

let each side be x

therefore

x^2 = 15^2 + 20^2
x^2= 225 + 400
x^2=625
x = 25

side of rhombus = 25 cm
