Step 1
Given that the total area of the rectangular pen is 216 square feet, we can set up the equation: 2x * y = 216 Solving for y, we get: y = 216 / 2x Since the dimensions of the two pens inside the rectangular pen are equal, we have: x = 12 ft y = 216 / (2*12) = 9 ft Show more…

A farmer has 160 yd of fencing material and wants to enclose three rectangular pens. Suppose that $x$ represents the length of each pen and $y$ represents the width as shown in the figure. a. Assuming that the farmer uses all 160 yd of fencing, write an expression for $y$ in terms of $x$. b. Write an expression in terms of $x$ for the area of one individual pen. c. If the farmer wants to design the structure so that each pen encloses $250 \mathrm{yd}^{2},$ determine the dimensions of each pen.
