7. The figure shows a proposed sand pit,
an area in a park that will be filled with
sand. The sand pit is to be a large
rectangular area twice as long as it is wide,
plus a smaller rectangular area 3 feet long and
as wide as the large area. The two areas share a
common side. a. Write an expression for the
total perimeter of the sand pit as a
function of x. b. Write an expression for the
total area of the sand pit as a function of
x. c. The sand in the pit is to be 3 inches
deep throughout. The park has 40 cubic
feet of sand available. What will be the
approximate dimensions of the sand
pit? d. The pit is to be bordered by a chain
link fence. How much fencing is needed?
