Question

The length and breadth of hall is 12.5m and 8m respectively. If the room is to be carpeted, what is the area of the carpet required?​

Answer 1

Answer:

length= 12.5m= 1250cm (converted into cm)

breadth= 8m= 800cm (converted into cm)

area of a rectangle= l x b

                               = 1250 x 800

                               = 1000000cm

                               = 10000m (converted into meter)

So, he area of the carpet required is 10000m.

Answer 2

Answer:

100$m^{2}$

Step-by-step explanation:

Given the length and the breadth, we can infer that the shape is a rectangle.

The formula for the area of the rectangle is:

A = length x width (or breadth).

So we multiply 12.5m by 8m (and we don't have to do any conversions because the values given in the question are already in the standard unit, metres).

12.5 x 8 = 100

m x m = $m^{2}$ (if you find this difficult, don't worry. Just memorize the standard unit for area, which is $m^{2}$).

This is why we get 100$m^{2}$. It would be enough to cover the floor because it is the area of the floor.

Good luck, student!
