You have $7000 with which to build a rectangular enclosure with fencing. The fencing material costs $30 per meter. You also want to have two partitions across the width of the enclosure, so that there will be three separated spaces in the enclosure. The material for the partitions costs $25 per meter. What is the maximum area you can achieve for the enclosure

1857.12 square meters

Step-by-step explanation:

Let L be the length of the rectangle and 'W' be the width

Perimeter =

The fencing material costs $30 per meter.

The material for the partitions costs $25 per meter

Solve for L

Area = length times width

Now take derivative and set it =0

set the derivative =0  and solve for W

So width = 31.8 that gives maximum area

square meter

i would say b) is your answer

sorry if im wrong
