Question

If we are using area of trapezium to find area of parallelogram then the parallel sides of trapezium are .

• A. equal
• B. different
• C. non - parallel

Answer 1

The correct option is A equal


If we are using area of trapezium to find area of parallelogram then

Area of parallelogram
= $\frac{1}{2}$$\times$(Sum of parallel sides)$\times$height
Here parallel sides are equal AB=CD.

$⟹$Area of parallelogram
= $\frac{1}{2}$$\times$(AB+CD)$\times$BE
= $\frac{1}{2}$$\times$(2CD)$\times$BE
= CD$\times$BE
= base$\times$height
