Your neighbor has a backyard with an area 450 square feet. He decides to place a sandbox for his children in a section of his backyard which is 32 square feet. Determine the perimeter of your neighbors back yard, as well as the perimeter of the sandbox. (Hint: adding simplified radicals is similar to adding fractions – like radicals can be combined!) In your response we sure to clearly articulate your thinking as to your process for solving, as well as a justification for your reasoning.
