Answer:

$1.20

A farmer wishes to enclose a rectangular pasture with 1200 ft of fence. He needs to divide this rectangle into two smaller recta
Minchanka [31]

Answer:60,000 ft^2

Step-by-step explanation:

Given

total of 1200 ft of fence is available

Suppose rectangular pasture has following dimension as shown in figure.

total perimeter

P=4a+3b

1200=4a+3b

4a=1200-3b

a=300-\frac{3}{4}b

Area of rectangle is

A=2a\times b

A=2(300-\frac{3}{4}b)b

A=2[300 b-\frac{3}{4}b^2]

For maximum area, differentiate A w.r.t b

\frac{\mathrm{d} A}{\mathrm{d} b}=300-\frac{3}{2}b=0

300=\frac{3}{2}b

b=200 ft

so a=300-150=150\ ft

so area is

A=2\times 150\times 200

A=60,000 ft^2
