Answer 1

Answer:

1. The cost of flooring the verandah with marble at ₹ 236 per metre square is Rs. 18880

Step-by-step explanation:

Length of room = 10 m

Breadth of room = 6 m

It is surrounded by a verandah which is 2 m wide all around it.

Outer length = 10+(2+2)=14 m

Outer breadth = 6+(2+2)=10 m

Area of floor of verandah = (14 \times 10)-(10 \times 6)=80 m^2(14×10)−(10×6)=80m

2

Cost of flooring 1 sq.m. = Rs.236

Cost of flooring 80 sq.m. =80 \times 236= Rs.18880

Hence the cost of flooring the verandah with marble at ₹ 236 per metre square is Rs. 18880

New length = | = 14 m

New breadth = b = 10 m

Area = lxb = 14×10 = 140 m

Cost = areax615 = 140×615 = 86100 RS.
