Question

the area of parallelogram ABCD is 56 CM square find a b if DE =10 cm​

Answer 1

If DE = 10 cm and area is 56 cm² then AB is 5.6 cm.

Step-by-step explanation:

The area of the parallelogram ABCD = 56 cm

The length of the perpendicular height on the side AB of the parallelogram, DE = 10 cm

Let side AB be the base of the parallelogram ABCD.

We know that,

The formula of the area of the parallelogram is given by,

Area = [Base] * [Height]

Substituting the given values in the above formula, we get

Area = AB * DE

⇒ 56 = AB * 10

⇒ AB = $\frac{56}{10}$

⇒ AB = 5.6 cm

Thus, the length of side AB of the parallelogram is 5.6 cm.
