Solution

## 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 $=2\left(l+b\right)$ $=2\left(2.25+1.50\right)\phantom{\rule{0ex}{0ex}}=2x3.75\phantom{\rule{0ex}{0ex}}=7.50m$Hence the perimeter of the table top is $7.50m$.
