Question

A table top measures $2m25cm$ by $1m50cm$. What is the perimeter of the table top?

Answer 1

Given,

Length of the table top $\left(l\right)$ $=2m25cm=2.25m$ [$\because$ $1cm=0.01m$]

Breadth of the table top $\left(b\right)$ $=1m50cm=1.50m$ [$\because$ $1cm=0.01m$]

As perimeter of the table top is same as perimeter of the rectangle.

Therefore ,Perimeter of the table top $=2\left(l+b\right)$

$$\begin{gathered} =2(2.25+1.50) \\ =2x3.75 \\ =7.50m \end{gathered}$$

Hence the perimeter of the table top is $7.50m$.
