Question

ABCD is a parallelogram whose area is 54 $c{m}^2$.The area of triangle AEB is __ $c{m}^2$.

​

Answer 1

If a triangle and a parallelogram are on the same base and between the same parallels, then the area of the triangle is equal to half the area of the parallelogram.
Given:

Area of parellogram = 54 $c{m}^2$

$\text{Area of triangle AEB is}\frac{1}{2}\times 54=27c{m}^2$.
