Question

A room is $4m$ long and $3m50cm$ wide.

How many square meters of carpet are needed to cover the floor of the room?

Answer 1

Given

length of carpet $=4m$

breadth of carpet $=b=3m50cm=3.50m$

Find out

We have to determine the area in square meters

Solution

We know that area of a rectangle is given by

Area of rectangle = length $\times$ width

Area $=l\times b$

$$\begin{gathered} =4\times 3.50 \\ =14m^2 \end{gathered}$$

Hence, the area of carpet$=14m^2$
