Question

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

Answer 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.

Answer 2

the signs are wrong the signs in the front of the equation should be equal to or less then and equal to or grater then
