Question

A rectangular pen with a perimeter of 60FT is needed to house three pigs. Determine an equation to model the area of this pen

Answer 1

x*y=a
2x+2y=60 (in case you needed perimeter equation)

Answer 2

I was thinking to use A=LxW
A= x (60-x)
A= 60x - x^2

Answer 3

x and y would be the length and width, sorry.

Answer 4

but you would need to use 60-2x, because the perimeter contains 2 widths and 2 lengths.

Answer 5

So what would be the equation to find the area

Answer 6

you had it right, you would just need to change x(60-x) to x(60-2x) then simplify

Answer 7

how would i simply it

Answer 8

simplify *

Answer 9

\[2x+2y = 60, x+y =30, x=30-y\]
\[A=length*width=y*(30-y) = 30y-^{2}\]
