W= width
l= 2w= length
Perimeter of a Rectangle Formula
P= 2(l + w)
substitute 2w for l in equation
180= 2(2w + w)
multiply 2 by parentheses
180= 4w + 2w
combine like terms
180= 6w
divide both sides by 6
30 yards= w
LENGTH
2w= 2(30)= 60 yards
CHECK:
180= 30 + 60 + 30 + 60
180= 90 + 90
180= 180
ANSWER: the width is 30 yards and the length is 60 yards
Hope this helps! :)

Answer:
A. 31.4 feet
Step-by-step explanation:
The formula for circumference is given by
C = pi d
Since we know the diameter is 10 ft
C = pi * 10
pi is approximately 3.14
C = 3.14* 10
C = 31.4 ft
-1/2x > 6
All you have to do is divide 6 by -1/2, which is -3. The answer is x < -3, the sign got flipped because you divide by a negative number.
