Question

ABCD and BCFE are parallelograms. If area of triangle $EBC=480c{m}^2$, AB = 30 cm and BC = 40 cm; Calculate : area of the parallelogram BCFE

Answer 1

Since area of $△EBC={480}^2$, area of parallelogram $ABCD=2\times 480=960{cm}^2$
Since, ABCD and BCFE are parallelograms with the same base and the sides are equal. area of parallelogram BCFE $=960{cm}^2$
