A cement pathway of uniform width is to be poured around a rectangular swimming pool measuring 16 feet wide by 28 feet long. Given that (16+2x) is an expression for
the width of the outer edge of the path and (28+2x) is an expression for the length of
the outer edge of the path, what would a quadratic in standard form for the area of
the path (remember to take the area of the pool away from the area of the whole
outer edge.
O A (20) = 4x2 +88x + 448
O A (2) = 4x2 +882
O A (2) = 2x2 + 440 + 448
O A (x) = 2.2 + 442
