Question

The cost of flooring a hall at Rs.12.50 per square metre is Rs.1000. If the width of the hall is 8m then find its length?

Answer 1

area = 1000÷ 12.50

$= 80{m}^{2}$

then

length = 80÷8 = 10 m

Answer 2

The length is 10 m

Step-by-step explanation:

Area floored at Rs.12.50 = 1 sq.m.

Area floored at Rs.1000 =$\frac{1000}{12.50}= 80 sq.m.$

Let l be the length of floor

Breath = 8 m

Area of floor =$Length \times Breadth = 8l$

So, $8 l = 80$

$l = \frac{80}{8}=10$

Hence The length is 10 m
