Justin draws a square with an area of 150 square centimeters. What is the approximate length, in centimeters, of one side of the square? A. 2cm B. 11cm C. 12cm D. 13cm

What we know:

Shape is square

Area = 150 cm²

Area=s²

What we need to find: s=side of square

Area=s²

150=s²

√150=√s²

√150=s

s≈12 cm

C. 12cm

Remember when finding the square root of a number you get a positive and negative solution. In this case, length is positive so we do not need the negative solution.
