A square has four equal sides to find he area of a square multiply one side by the other. If the square is 2by2by2by2 multiply 2x2 to get the area. In this case you already have the area. The area of a square can be defined as x^2 x being the length of a side = the area x^2=A substitute the value of the are x^2=37 to simplify this expression you have to cancel out the x^2 to x. Do this by using the square root. Square root of x squared is x remember you have to do this on both sides of the equation so the square root of 37 is something like 6.081937474728774738 or something and you have to round to the nearest tenth of an inch so.. The length of a side would be approximately 6.1 inches
