**Walker**, Thursday, April 30, 2009 at 10:04pmSince the formula for the a\area of a square is "Area=(side)^2", all the sides are equal. So just substitute in.

s^2=64

s=sqrootof64

side=8

8-3=5

so the original side length is 5 cm.

**Ms. Sue**, Thursday, April 30, 2009 at 10:05pmThe area of a square is the two sides multiplied together.

Since all sides of a square are the same, you need to find the square root of 64.

When you find that, subtract 3 cm from it to answer your question.
