2. Massimo and his friends were given 960 feet of rope in phys. ed class, so that they couldmake the boundaries of 3 equal sized rectangles where they would be playing socially distancedgames. The rectangles had to be connected to each other. Mr. Notice drew a quick sketch ofhow to arrange the rectangles. It was up to Massimo to calculate the dimensions that would givethe greatest possible area for each rectangle.Massimo created an equation where xwas equal to the width of one rectanglein feet and 480 − 2x was the length in feetof all three rectangles combined.Area(Three Rectangles) = (Width)(Length)Area(Three Rectangles) = (x)(480 − 2x) Show all work. Use the above equation, expand, simplify and complete the square.From the information you calculate, determine the following:a) The greatest possible area for one of the three rectangles.b) The dimensions of one of the rectangles.
