then area of carpet =300-176=124sq.m

the total cost will be =124×800=99200

Answer 2

The area of carpet is 176 sq. m and total cost of carpeting is Rs. 140800.

Step-by-step explanation:

Since we have given that

Length of room = 20 m

Width of room = 15 m

while carpeting, we will leave a margin of 2 meter all around it.

So, Length of carpet becomes

$20-2-2=20-4=16\ m$

Width of carpet becomes

$15-2-2=15-4=11$

So, the area of carpet required would be

$16\times 11=176\ m^2$

Cost of per meter square = Rs. 800

So, total cost of carpeting would be

$176\times 800=140800$

Hence, the area of carpet is 176 sq. m and total cost of carpeting is Rs. 140800.
