PLEASE HELP ASAP!!!! FULL ANSWERS ONLY!!!!

Blake wants to build a rectangular enclosure for his animals. One side of the pen will be against the barn, so he needs no fence on that side. The other three sides will be enclosed with wire fencing. If Blake has 950 feet of fencing, you can find the dimensions that maximize the area of the enclosure.

a) Let w be the width of the enclosure (perpendicular to the barn) and let l be the length of the enclosure (parallel to the barn). Write a function for the area A of the enclosure in terms of w . (HINT: First write one equation with w and l and one equation with w and l and A. Solve for l in the first equation and substitute for l in the other). A ( w ) = ____________

b) What width w would maximize the area? w = __________________ ft

c) What is the maximum area? A = ______________ square feet

Answer: The width that would maximize the area would be 475, and the square feet would be 475.

Step-by-step explanation: 950 divided by 2 is 475 which would divide each of the two sides of the fence, to acquire the amount needed.
