The lengths of the diagonals of a rhombus are 16 cm and 30 cm, respectively. What is the perimeter of the rhombus?
The lengths of the diagonals of a rhombus are 16 cm and 30 cm, respectively.
perimeter of the rhombus =Â $$2\times\ \sqrt{\ \left(length\ of\ the\ diagonal_1\right)^2\ +\ \left(length\ of\ the\ diagonal_2\right)^2}$$
= $$2\times\ \sqrt{\ \left(16\right)^2\ +\ \left(30\right)^2}$$
= $$2\times\ \sqrt{\ 256+\ 900}$$
=Â $$2\times\ \sqrt{\ 1156}$$
= $$2\times34$$
= 68 cm
