Question

If a parallelogram of area $100{\text{cm}}^2$ is divided along its diagonal, then the area of a triangle formed equals ${\text{cm}}^2$.

• A. 25
• B. 50
• C. 150
• D. 100

Answer 1

The correct option is B 50

When a parallelogram is divided along its diagonal, we get two congruent triangles.
$⟹\text{Area of the triangle}=\frac{\text{Area of parallelogram}}{2}$
= $\frac{100}{2}{\text{cm}}^2$
= $50{\text{cm}}^2$
