A.) write a polynomial expression in simplified form, that represents the area of the pool. Show and explain how you got the area of the pool. Mrs. smith wants to add 2 foot concrete walkway around the edge of the pool. B.) Write a polynomial expression , in simplified form, that represents the total area of the pool and walkway. Show and explain how you got the area of the pool and the walkway. Mr. smith is unhappy with the 2 foot concrete walkway around the edge of the pool. He decides to put a different width around the pool. The total area of the pool and the walkway is given by the polynomial W^2+17W+66, where W represents the width of the pool. C.)
