Question

sorry everyone please answer number 8 also​

Answer 1

Answer:

base & height is 18cm and 6cm respectively

Explanation

In a parallelogram,

▪️height = ⅓ of base

▪️area = 108cm²

If we assume the base as ‘x'

Then, the height will be ⅓ of ‘x'

Or, height = x/3

We know that,

Area of a parallelogram : base • height

According to the question :

→ 108 = x • x/3

→ 108 = x²/3

→ 108*3 = x²

→ 324 = x²

→ √324 = x

→ 18 = x

∴ The base of the ||gm is 18cm.

Hence, height is : ⅓ of 18 = 6cm.
