Question

find the cost of carpeting a room 12 m long and 8 M broad with a carpet 75 M broad @ 116.50 per metre

Answer 1

Lateral surface area of cuboid =2(l+b)
For this sum with carpet, 2(l+b)+l*b
2(12+8)+12*75
932m^2
Therefore
116.50*932
=Rs.108,578

Answer 2

A N S W E R:

Lateral surface area of cuboid

=2(l+b)

For this sum with carpet,

2 (l+b) l × b

2 (12+8) + 12 × 75

932m^2

Thus,

116.50 × 932 = Rs.108,578

Ans: the cost of carpeting a room will be Rs. 108,578
