Question

Find the area of the adjoining parallelogram and hence find the value x.
​

Answer 1

Answer:

x = 160 cm

Step-by-step explanation:

In the given figure,

LMNO is ||gm so opposite sides are equal.

• LM = ON
• MN = LO

Considering base of ||gm as ON, it's height is PM.

Area of ||gm = Base × Height

Area of ||gm = 20cm × 8cm

Area of ||gm = 160cm²

Considering base of ||gm as MN, it's height is OQ.

Area of ||gm = Base × Height

160cm² = 10cm × x

160cm²/10cm = x

16cm = x

So required value of x is 160cm.
