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
I think it’s an equilateral triangle meaning all sides are the same so:
2x+2x+2x= 180 (that’s how much a triangle is)
6x=180 divide both sides by 6
x= 30
each side is 60 degrees

For this you can look at Sin Cos and Tan
A useful tip is S O/H C A/H T O/A
In this angle you have an opposite and an adjacent side to angle h.
So you’ll use Tan
You get
tan(x)= (2)/2root3
then you need to isolate the x value through the inverse of tan.
x= tan-1((2)/2root3)
x= 30
In a easier way you could’ve identified this as a 30,60,90 triangle from the side lengths.
