Question

Determine the areas and perimeters and match the pairs correctly.

• A. $36$
• B. $48$
• C. $50$

Answer 1

The first figure is a rectangle with length of $12$ cm and breadth of $4$ cm.

$l=12$ cm and $b=4$ cm
area $=l\times b=12\times 4=48$

The next figure is a square of side $9$ cm


The perimeter is sum of all sides
$=9+9+9+9=36$ cm

And the final figure is again that of a rectangle with sides $10$ cm and $5$ cm.


Therefore, area $=l\times b=10\times 5=50$
