Question 3

A table-top measure 2 m 25 cm by 1 m 50 cm. What is the perimeter of the table-top?

Answer 1

The perimeter of a closed figure is the length of its boundary.

Since
$1m=100cm$
$1cm=\frac{1}{100}m$

Length of table top
$=2m25cm=2.25m$

Breadth of table top
$=1m50cm=1.50m$

Perimeter of table top
$=2\times \text{(length + breadth)}$

$=2\times (2.25+1.50)$

$=2\times 3.75$

$=7.50m$

Thus, the perimeter of table top is 7.50 m.
