Question

The base and height of a parallelogram are 5 cm and 8 cm respectively. Find the area of the triangle formed by one of the diagonal with the adjacent sides of the parallelogram.

Answer 1

Area of the parallelogram = Base × Height = 5 × 8 = 40 $c{m}^2$

Area of the required triangle = $\frac{Areaofparallelogram}{2}$ = 20 $c{m}^2$
