 Question 122435: Please help. A rancher has 100 meters of fencing to enclose two adjacent rectangular corrals. 4x + 3y = 100 Write the area A of the enclosed region as a function of x So far this is what I’ve got-I figured out the function of x and plugged it into the Area formula, but that’s where I get stuck. P = 100 4x + 3y = 100 4x + 3y – 3y = – 3y + 100 A = 2x(y) I know x = 10 and y = 20 works for the perimeter, but don’t know how to write it to show that. When I graph (making A correspond to y and the y correspond to the x), I don’t get the same area as in the table. I need to add more values to the table. X Y Area 2 92/3 368/3 ≈123 4 28 224 Thank you for any help you can give!!! Click here to see answer by scott8148(6628)
