Question

A table-top measures 2m 25cm by 1m50cm.What is the perimeter of the
 table-top?

Answer 1

Hint:The table top is always in the form of a rectangle. So, to find the perimeter of
 the table top, we will apply the formula of perimeter of a rectangle and solve it.

Always in a rectangle, the length of rectangle will be more than its width
So, from the given data , we can write
The length of the table top=2m25cm=2.25m
Width of the table top=1m50cm=1.5m
We know the perimeter of rectangle is given by the formula=$2[length + width]$
So, we get Perimeter=$2[2.25 + 1.50]$
                                 =$2[3.75]$
                    Perimeter=$7.50m$

Note: Always write the appropriate unit associated with the solution.
