Answer 2

Answer:

Hence, Area of square having side 20 cm will be 400 Sq. cm

Step-by-step explanation:

In context to question asked,

We have to determine the area of the square.

As per question,

We have,

Side of square = 20 cm

As we know that,

Square is a quadrilateral whose all sides are equal.

The area of square can be determined by using the formula $Area = Side^2$

So, for determining the area of square we will put the value of side of square in above formula,

Thus we will get the area of square as,

$Area = 20^2\\=>Area = 20\times 20\\=>Area = 400\:cm^2$
