a farmer wishes to enclose two identical adjoining rectangular pens against the side of a large barn. she wants each pen to have an area of 750 square feet and will use the barn as one side of the enclosure. what is the least amount of fencing needed (in feet) to create the two pens?

Respuesta :

Using basic geometry and area formula for calculation of length, Apply fencing on only 3 side , The answer is 109.54 feet.

What do you mean by geometry?

A subfield of mathematics called geometry examines the dimensions, placements, angles, and sizes of objects.

What is a rectangle and it's formula for area?

A plane shape, as opposed to a square, with four straight sides and four right angles, particularly one with uneven neighboring sides.

Area of rectangle is:

A= l x b

area=750 square feet.

for attaining minimum area , these area must be fitted in square,

so, [tex]l = \sqrt {750}[/tex]

=27.38 feet

since, one side is taken by barn, l should be extended 4 times, 2 on 1 side and 2 on sides each.

Total length of fence = 4 * 27.38

= 109.54 feet
