Question 120423
If the sides of a square are increased by 3 inches., the area becomes 64 inches^2. Find the length of a side of the original square.
:
Let x = side of the original square
Then
(x+3) = side of the new square with an area of 64 sq/in
:
A simple equation:
(x+3)^2 = 64
:
Conveniently we can find the square root of both sides easily 8*8 = 64, right
x + 3 = 8
x = 8 - 3
x = 5 inches is the length of the side of the original square
:
:
(5+3)^2 = 64, right?

That was not so hard was it.
