A farmer has 250 ft of fencing and wants to enclose a rectangular area of 3750 ft². What dimensions should she use?

umka2103 [35]

Answer:

Longer side is 75 feet, shorter side is 50 feet.

Step-by-step explanation:

Let l be the length of the longer side and w be the length of the shorter side.

2l + 2w = 250, which simplifies to

l + w = 125. Solving for w, we have

w = 125 - l.

lw = l(125-l) = 3750

${l}^{2} - 125l - 3750 = 0$

$( l - 50)(l - 75) = 0$

l = 75, w = 50
