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.
