Question

A hall room is 28 m long and 18m wide find the cost of carpeting the floor with a carpet 0.75m wide at the rate 12.50 per metre

Answer 1

refer to the attachment

$cost = RS \: 7 \: nd \: remaining \: area = 503.4m ^{2}$

Answer 2

Cost of carpeting is 8400 rupees.

Step-by-step explanation:

Given:

A hall room long =L = 28 m.

Wide = 18 m.

Area of room = $L\times B$

                      = $28\times18$

                     = $504 m^2$

The floor with a carpet = 0.75 m

Now,

$\frac{Area of room}{floor with a carpet}$,

= $\frac{504}{0.75}$

= 672

Cost of carpeting at the rate 12.50 per metre = $672 \times12.50$

                                                                           = 8400 rupees.
