A rancher is putting up a rectangular electic fence to contain some horses. The rancher has 1200 feet of electric wire. The fence needs to be at least 120 feet in one direction in order to contain the barn.

Which system of linear equalities describes the conditions in this problem?

a)2w + 2l >= 1200, w >= 120
b)2w + 2l <= 1200, w <= 120
c)2w + 2l >= 1200, w <= 120
d)2w + 2l >= 1200, w >= 120

1. look at w, that means a or d is the answer. Then, look at perimeter, 2l+2w has to be less than 1200 ft. So, no answer is right, if you typed them correctly.
