how do you find the base of a rectangle
Thanks for answering anonymous but you did make a little mistake.
To find one side if you know the other and the area is simple;
follow this simple equation:
A = L1*L2
therefore
L2 = A / L1
The rest is good.
A-L1=L2
where:
A= area
L1= length of known side.
L2= length of unkown side.
