Question

Let ABCD be a parallelogram of area 124 cm². If E and F are the mid-points of sides AB and CD respectively, then find the area of parallelogram AEFD.

Answer 1

Answer:

Area of parallelogram AEFD is 62 cm²

Step-by-step explanation:

Solution↴

ABCD be a parallelogram.

Area of parallelogram = 124 cm² (Given)

Consider a point P and join AP which is perpendicular to DC.

Now,

Area of parallelogram EBCF = FC x AP and

Area of parallelogram AFED = DF x AP

Since

F is the mid-point of DC, so DF = FC

From above results, we have

Area of parallelogram AEFD = Area of parallelogram EBCF = 1/2 (Area of parallelogram ABCD)

= 124/2

= 62

Area of parallelogram AEFD is 62 cm²
