Answer:
w=21 ft.
l=42 ft.
Step-by-step explanation:
It says that the length is twice the Width
The perimeter is 126 ft.
w will represent width.
So, length=2w
Perimeter involves adding. So, p= 2length + 2width.
126 ft. = 2(2W) + 2W
126(represents perimeter) = 2(2w) + 2w
126 = 4w+2w
126= 6w
divide both sides by 6.
w=21 ft.
After finding the width, we know in order to find the length, it has to be twice the amount of the width. So, 21x2.
Resulting in:
width= 21 ft.
length= 42 ft.
