The area of the square is 2500 cm2. What is its side equal to? Find the perimeter of this square.

Given:
S square – 2500 cm2
Find:
a – ? cm
R – ? cm
Solution:
we derive from the formula for finding the area of a square, the formula for finding the side of a square:
S squared = a squared
hence a = Root of S
a square = root 2500
a square = 50 cm
now we can find P of the square
P = a * 4
P = 50 * 4
P = 200 cm
Answer: P of a square is 200 centimeters.
