Total area of the four pens? So, estimate it.
(b) Draw a diagram illustrating the general situation. Let x denote the length of each of two sides and three dividers. Let y denote the length of the other two sides.
(c) Write an expression for the total area A in terms of both x and y.
A = xy
(d) Use the given information to write an equation that relates the variables.
5x + 2y = 325
(e) Use part (d) to write the total area as a function of one variable.
A(x) = 325x - (5/2)x^2
(f) Finish solving the problem by finding the largest area (in ft^2).
ft^2
Total area of the four pens?
Rectangular area A and then divide it into four pens with fencing parallel to one side of the rectangle. What is the largest possible?
(a) T Draw several diagrams, so estimate it.
(b) Draw a diagram illustrating the general situation. Let x denote the length of each of two sides and three dividers. Let y denote the length of the other two sides.
(c) Write an expression for the total area A in terms of both x and y.
x * y
(d) Use the given information to write an equation that relates the variables.
5x + 2y = 325
(e) Use part (d) to write the total area as a function of one variable.
A(x) = 325x
