The answer is 56 ft
The perimeter of the rectangle with width w and length l is:
P = 2w + 2l
We know:
w = 7 ft
l = 3w = 3 * 7 = 21 ft
P = 2w + 2l
P = 2 * 7 + 2 * 21
P = 14 + 42
P = 56 ft

Angles 1 and 4 are alternate angles and thus have the same measurement. You will set their equations equal to each other and solve for the variable.
6n + 1 = 4n + 19
Subtract 1 and 4n from both sides to get variables on one side and constants on the other.
6n - 4n = 19 - 1
Combine like terms and solve for n.
2n = 18
n = 18 / 2
n = 9
Angles 1 and 2 are congruent as labeled in the graph.
So angle 2 is also 6n + 1
Plug in for 9 for n
6(9) + 1
54 + 1
55
