Answer:

Step-by-step explanation:

P = 2(L + W)

P = 950 feet

L = 3W - 65

W = W

950 = 2 * (L + W)              Divide by 2

950/2 = 2*(L + W)/2

475 = L + W

475 = 3W - 65 + W          Add 65 both sides. Combine W on the right.

475 + 65 = 4W + 65 - 65

540 = 4W                           Divide by 4

540/4 = 4W/4

135 = W

=========================

W = 135

L = 3*135 - 65 = 340
