WORD PROBLEMS-GEOMETRY VOLUME 1. A square has an area of sixteen square centimeters. What is the length of each of its sides? The formula for the area A of a square with side length s is: A = s 2 They gave me the area, so, plug this value into the area formula and see where this leads: 16 = s 2 4 = s ___________________________________________________ 2. A circle has an area of 49 square units. What is the length of the diameter of the circle? The formula for the area A of a circle with radius r is: A = (pi) r 2 the radius r is half the length of the diameter d, so: 49 pi = (pi) r 2 (49 pi) / pi = [(pi) r 2] / pi 49 = r 2 7 = r https://www.purplemath.com/modules/perimetr.htm
