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.8.50Costofflooringpersquaremeter=Rs.8.50
\sf \implies Total \: cost \: of \: flooring \: of \: room = Rs.510⟹Totalcostofflooringofroom=Rs.510
\sf∴ Area \: of \: the \: room = \frac{510}{8.50} = 60 \: m {}^{2}∴Areaoftheroom=
8.50
510
=60m

Formula used :- ( Area of rectangle )
\sf \pink{ Area \: of \: the \: room = l×b}Areaoftheroom=l×b
Calculation...
\sf \purple\implies 60=8×b⟹60=8×b
\sf \purple\implies b = \frac{60}{8} = 7.5 \: m⟹b=
8
60
=7.5m
\red{\boxed{ \sf∴ Breadth \: of \: the \: room \: is \: 7.5 \: m}}
