Answer 1

Corrected Question :

• The length and breadth of a room are 18 m and 8 m respectively. Find the cost of covering the floor with tiles at the rate of ₹ 100 per square metre.

To Find : The cost of covering the floor with tiles ?

❍ Finding Area of the floor of Room by the formula is given by :

• $\boxed{\sf\pink{Area_{(Rectangle)}~=~l~×~b}}$★

Solution : Here l is the length of Rectangle in metres and b is the Breadth of Rectangle in metres and we have given with length and breadth of a room are 18 m and 8 m respectively.

$~~$

$\underline{\bf{Now~ By~ Substituting~ ~the ~Given~ Values~ :}}$

$:\implies{\sf{Area_{(Floor\: of \:Room)}~=~18~×~8}}$

• ${\underline{\boxed{\frak{\pink{Area_{(Floor \:of \:Room)}~=~144~m^2}}}}}$★

Therefore,

$~~~~~~~~~~~$${\sf{Area~of~Room~is~144~m^2}}$

$~~~~~~~~~$____________________

❍ Finding Cost of covering the floor of Room with tiles by the formula is given by :

$\boxed{\sf\pink{Total~Cost~=~Area \:of \:floor\:×\:Cost\: at \:the \:rate \:of \:m^2}}$

• Here Area of Room is 144 m² and the cost of rate per square metre is Rs. 100 per square metre.

$~$

$\underline{\bf{Now~By~Susbtitung~the~Given~Values}}$

:$\implies{\sf{Total~Cost~=~144~×~100}}$

• ${\underline{\boxed{\frak{\pink{Total~Cost~=~Rs.~14400~m^2}}}}}$★

$~$

Hence,

$\therefore\underline{\sf{Total~Cost~of~Room~flooring~with~tiles~is~Rs.~14400}}$
