Ratio of area of ∆MNO to the area of parallelogram MNOP in the same figure 9.17 is
a. 2 : 3
b. 1 : 1
c. 1 : 2
d. 2 : 1

Solution:

We know that

Area of ∆MNO: Area of parallelogram MNOP = 1/2 × b × h: b × h

It can be written as

= 1/2 × NO × OQ: MP × OQ

So we get

= 1/2 × NO: NO [As NO = MP]

= 1 : 2

Therefore, the ratio is 1 : 2

✦ Try This: 8 hectare = ____ cm²

We know that

1 hectare = 10,00,00,000

So we get

8 hectare = 80,00,00, 000

Therefore, 8 hectare = 80,00,00,000 cm²
