Because, well, without them how are you able to add and subtract fractions :D
It is according to the laws of mathematics that you cannot add or subtract fractions that have different denominators to each other. So you need to make your fractions having the same denominator so that they are able to be added or subtracted (hence the equivalent fractions - making the denominators the same are making the fractions equivalent)
The formula for the area of a square is:
A = s²
Area = side²
We know that area (A) is 20 ft²
20 = s²
Now we must find the length of the side (s). To do this we must get rid of the square. To remove the square from s take the square root of both sides:
√20 = √s²
s ≈ 4.5 ft <<< approximate answer
To find the exact answer you must simplify the square root:
s = 2√5 ft <<< exact answer
Each side of the square is exactly 2√5 or approximately 4.5
Hope this helped! Let me know if you have any further questions
