Question

The area of square is 225 cm² find the perimeter of square will be

Answer 1

Answer: 60 cm

Step-by-step explanation:

Let the length of a side of the square is L cm.

Then the area is $L^{2} cm^{2}$

Now, $L^{2} = 225$ ⇒ $L =$ ± 15

Since, length can not be negative, So L=15 cm

Now, perimeter of the square is 4×L=4×15=60 cm
