Answer 1

Question⇰

The total cost of flooring a room at Rs.8.50 per sq. metre is Rs.510. If the length of the room is 8 metres, find its breadth ?

Given :-

Flooring of a room = ₹ 8.50

Per square Metre = ₹ 510

Length = 8 m

To find :-

• Find its breadth

Let's Do...!

$\sf \: Cost \: of \: flooring \: per \: square \: meter = Rs.8.50$

$\sf \implies Total \: cost \: of \: flooring \: of \: room = Rs.510$

$\sf∴ Area \: of \: the \: room = \frac{510}{8.50} = 60 \: m {}^{2}$

Formula used :- ( Area of rectangle )

$\sf \pink{ Area \: of \: the \: room = l×b}$

Calculation...

$\sf \purple\implies 60=8×b$

$\sf \purple\implies b = \frac{60}{8} = 7.5 \: m$

$\red{\boxed{ \sf∴ Breadth \: of \: the \: room \: is \: 7.5 \: m}}$

Answer 2

Answer: 7.5m

Step-by-step explanation: Answerable

Step-by-step explanation: Cost of flooring per square meter  = 8.50 rupees.

              Total cost of flooring of room = 510 rupees

               Therefore, Area of the room =510 ÷8.50 =60

                there fore we know that area = length *breadth

                 if length of the room = 8 meters then breadth = area/length = 60m²/8 = 7.5m
