Question

Revanth has a rectangular lawn of length 45 m and breadth 20 m in his garden. He wants to do flooring 5 m along outside the lawn for path. Find out the area of path. Find the cost of flooring at the rate ` 100 per sq.m​

Answer 1

Answer:

length= 45+5= 50 m

breadth= 20+5=25m

area= 50*25=1250 sq.m

rate = 100 *1250 sq.m=125000

Answer 2

Given,

The rectangle-shaped lawn's length is 45m.

And the breadth = 20m.

The outer path is 5m.

To Find,

The outer path area and money needed to flooring it.

Solution,

The length of the inner side of the rectangle is 45m

The breadth of the rectangle's inner side is 20m.

The area of the lawn = b*l

A1 = 45*20

A1 = 900m²

The outer side length of lawn = 45+5+5

l = 55m

And the breadth b = 20+5+5

b =30m

Therefore area A2 = 55-30

1650m²

Therefore,

the path's area = A2-A1

1650 - 900 =750m²

And the total money need for flooring = 100 * 750

75000rs.

Hence, the lawn has a 750m² outer path and needs 75000rs for flooring the entire path.
