Question

The area of a rhombus is 72 cm².If one of the diagonals is 18 cm long,find the length of the other diagonal.

Answer 1

length of the other diagonal is 8cm

Answer 2

Area  of rhombus = product of its diagonals × $\frac{1}{2}$
                      72  = 18 × other diagonal × $\frac{1}{2}$
                  72/9 = other diagonal
                        8  = other diagonal


Length of other diagonal = 8cm
