Answer 2

Given :

A piece of string 28 cm long is bent to form the square

To find :

what is the area of the square

Solution:

Length of string = 28 cm

Perimeter of square = $4 \times Side$

So,$4 \times Side = 28$

$Side = \frac{28}{4}$

Side = 7

Area of square = $Side^2 = 7^2 = 49 sq.cm.$

Hence The area of square is 49 sq.cm.
