If the measure of two diagonals of a rhombus are 15 meter and 20 meter, then let us write by calculating its perimeter, area and height.

Given, the measure of two diagonals of a rhombus are 15 meter and 20 meter.

Formula used:


Area of a rhombus = ×product of length of diagonals of Rhombus.


Area of a rhombus = × 15 × 20


= 150 sq. cm
