Question The length of the rectangle is six times it’s width. If the perimeter is 84yd find the length and width

Answer: W = 6 L = 36 Step-by-step explanation: 2L + 2W = 84 L = 6W Substitute for L in the first equation 2 (6W) + 2W = 84 12W + 2W = 84 14W = 84 W = 6 Substitute W in the first equation 2L + 2(6) = 84 2L + 12 = 84 2L = 72 L = 36 Plug both values in both equations to be sure 2(36) + 2(6) = 84 36 = 6 * 6 Hope that helps!

Answer:W = 6

L = 36

Step-by-step explanation:2L + 2W = 84

L = 6W

Substitute for L in the first equation

2 (6W) + 2W = 84

12W + 2W = 84

14W = 84

W = 6

Substitute W in the first equation

2L + 2(6) = 84

2L + 12 = 84

2L = 72

L = 36

Plug both values in both equations to be sure

2(36) + 2(6) = 84

36 = 6 * 6

Hope that helps!
