Photo A, B, C are all square photos. The area of Photo C is the same as that of a rectangular photo whose length is the side length of Photo A and whose width is the side length of photo B. Use the properties of rational exponents to write and solve an equation to find the side length of Photo A
Photo A - Area = x cm^2
Photo B - Area = 72 cm^2
Photo C - Area = 110 cm^2
