Question

The perimeter of the given polygon (in centimetres) is ___ cm.

Answer 1

To find the perimeter in centimeters, we have to convert all the dimensions into centimetres.

$1500mm=\frac{1500}{10}cm=150cm$

$2m=2\times 100cm=200cm$

$500mm=\frac{500}{10}cm=50cm$

$1m=1\times 100cm=100cm$. So, after converting all the dimensions to centimetres, the lengths of the sides of polygon are as follows:

Perimeter of the polygon (in cm) = (100 + 150 + 50 + 200 + 50 + 100) cm = 650 cm
