Question

Find the area of the rectangle whose sides are $2\text{m}$ and $70\text{cm}$.

Answer 1

• The area $A$ of the rectangle with length $l$ and width $w$ is given by, $A=l\times w$.
• Here the length is $2\text{m}$ which is equivalent to $200\text{cm}$ that means $l=200$ and the width is $70\text{cm}$ , that gives $w=70$.

Step 1: Substitute $200$ for $l$ and $70$ for $w$ into $A=l\times w$ and find the area of the rectangle.

$\begin{array}{rcl}A& =& 200\times 70\\ & =& 14000{\text{cm}}^2\\ & =& 1.4{\text{m}}^2\end{array}$

Hence, the area of the rectangle is $1.4{\text{m}}^2$.
