Question

find the breadth of the room if the cost of carpeting in 24 m long room 16per square metre is rupees 3840

Answer 1

Answer:96m

Step-by-step explanation:length(l) = 24m

Breadth=b

Total cost=Rs.3840

Cost per square metre=16 Rs.

Total cost =area of rectangle ×cost per metre square

3840= [2(l+b)] × 16

3840/16=2×l+2×b

240=2×l+2×24

240=2×l+48

240-48=2×l

192=2×l

192/2=l

l=96m
