The length of a rectangle, i, is six meters more than it's width, w. if the perimeter of the rectangle is 36 meters what is the length of the rectangle, in meters

Length = 12 meters

Step-by-step explanation:

Rectangle

Perimeter P = 2(L + W)

The length of a rectangle, I, is six meters more than it's width, W.

Then L = W + 6

So

P =  2(W + 6 + W)

P = 2 (2W + 6)

P = 4W + 12

Plug in P = 36 meters

36 = 4W + 12

4W = 36 - 12

4W = 24

 W = 6 meters

L = 6 + 6

L = 12 meters

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
