Question

9. One side and corresponding altitude of a parallelogram are 50 cm and 8 cm. If the other altitude is 4 cm, find the length of other pair of parallel sides.​

Answer 1

Answer:

BN = 100 cm. Refer the attachment for figure.

Step-by-step explanation:

Here,

Let AB = 50 cm, DM = 8 cm.

Let other altitude BN = 4 cm,

then, AD = ?

We know,

Area of parallelogram = one side × corresponding altitude.

So, AB × DM = AD × BN

50 × 8 = 4 × BN

BN = 100 cm.
