Abuilding in a city has a rectangular base. the length of the base measures 65 ft less than three times the width. the perimeter of this base is 950 ft. what are the dimensions of the base?

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

180
