Question

11. How many metres of carpet 75 cm wide will be required to cover
a floor 27 m by 16 m, and what will be the cost at Rs 30 a metre?
​

Answer 1

Answer:

First find the surface area of floor.

Step-by-step explanation:

Surface area of floor = length * breadth

= 27*16= 432 m^2

Let the lenght of carpet be x meter

and wide =75cm= 0.75m

Surface area of carpet = surface area of floor

length * breadth = 432

0.75 * X =432

X = 432/0.75

X = 576 m

So a total of 576 meter long carpet is required.

Total cost = 576*30

=Rs. 17280
