Question

Find the perimeter of the square whose sides is$12m50cm$

Answer 1

Finding the perimeter of the square:

Perimeter of the square=$4a$

where $a$ is the edge of the square

we know that,

$$\begin{gathered} 1m=100cm \\ 12m=12\times 100 \\ =1200cm \\ 12m50cm=1200+50 \\ =1250cm \end{gathered}$$

Perimeter of the square$=4\times 1250$

$=5000cm$

Hence the perimeter of the square =$5000cm$
