Question

A square has a side of $4$ cm. Will its area be equal to its perimeter?

• A. Yes
• B. No

Answer 1

The correct option is A Yes

We know that, for a square, area is equal to multiplication of its side.

Here, the side $=4$ cm
Therefore, area $=4\times 4=16$ square cm

And perimeter of a square is sum of all the four sides.

So, perimeter $=4+4+4+4=16$ cm

So, we see that in this case, the area $=$ perimeter.

It should also be noted that while the value of the area and perimeter are equal, their units will be different.

Also, the area and perimeter of a square will not always be equal.

For example, if a square has $=5$ cm
its area $=5\times 5=25$ square cm

Thus this is a special case scenario, not a rule.

Perimeter $=5+5+5+5+5=20$ cm
