Example Problems

Problem 1:
Find the area of a square with a side length of 10.
Solution:
1.) Plugging the side length into the formula, we get:
A = s2
A = 102 = 100
2.) The area of the square is 100.

Problem 2:
A square’s area is measured to be 81 square meters. What is its side length in meters?
Solution:
1.) Let’s plug the area into the formula first.
A = s2
81 = s2
2.) Now let’s solve for the side length s.
81 = s2
s = 9
3.) The side length is 9 meters.
