​

Answer 1

$\mathfrak{\huge{Answer:}}$

$\mathbb{GIVEN}$

Breadth of room = 6 m

Cost of carpeting the room = Rs. 4.50 per square metre

Total cost for carpeting the room = Rs. 135

$\mathbb{TO\:FIND}$

Length of the room

$\mathbb{METHOD}$

We're Given with the cost of one square metre and the total cost for the given room. We know that :

Cost of carpeting = Area of the room × Cost per square metre

=》 135 = Area of the room × 4.50

=》 Area of the room = 30 sq. m

Breadth of the room is given to be as 6 m. Now, the final step is to find the length of the room. We know that :

Area = Length × Breadth

=》 30 = Length × 6

=》 Length = 5 m

Thus, the final answer will be $\tt{\huge{5\:metres}}$
