Question 580068
A small square is constructed. Then a new square is made by increasing each side by 2 meters. 
The perimeter of the new square is 3 meters shorter than 5 times the length of one side of the original square.
 Find the dimensions of the original square. 
:
Let x = the length of the side of the original square
and
Let (x+2) = the side of the new square
then
4(x+2) = the perimeter of the new square
:
"The perimeter of the new square is 3 meters shorter than 5 times the length of one side of the original square."
4(x+2) = 5x - 3
4x + 8 = 5x - 3
8 + 3 = 5x - 4x
11 = x
:
the original square is 11 by 11
