Question

A carpet is to be laid down in a square hall of side 6 m, leaving 25 cm space from the four walls of the hall. What will be the cost of the carpet at ₹ 120 per m2​

Answer 1

Given -

a = 6m/ 600cm

cost for 1m^2 = ₹ 120

Formula -

Area of a sqaure = a^2 / (side)^2

Solution -

By leaving 25 cm from all the four walls, all sides will become 575cm in length.

Now, we have to find the area of this to determine the carpet laying area.

Therefore, 575 * 575 = 330625cm^2

Now, since 1m^2 = ₹ 120,

we have to convert cm^2 onto m^2

330625/10000 = 33.0625m^2

Cost for 33.0625m^2

= 33.0625 * 120

=  ₹ 3967.5
