Question

the cost of flooring a room is Rs 1440.the rate of flooring is Rs 30 per sq.metre.if the room is 8m long,find its breadth

Answer 1

Cost=Rs1440
Rate=Rs30 per m^2
Cost=Area×Rate
1440=A×30
A=48m^2
A=l×b
48=8×b
b=6m

Answer 2

The breadth is 6 m

Step-by-step explanation:

Cost of flooring 1 sq.m. = Rs.30

The cost of flooring a room is Rs 1440

So, Area of floor =$\frac{1440}{30}=48m^2$

Length of floor = 8 m

Let x be the breadth of floor

Area of floor = $length \times Breadth = 8 \times x = 8x$

So,$8x=48$

x=6 m

Hence the breadth is 6 m
