Answer:
L=2.5
Step-by-step explanation:
P=2l+2w
The function given has the variables p, l, and w.
p = perimeter = 35
l = length = ?
w = width = 15
substitute the given values into the function.
p = 2l + 2w
35 = 2l + 2(15)
35 = 2l + 30
Subtract 30 from both sides of function.
5 = 2l
Divide both sides of the function by 2.
2.5 = l
The length is 2.5 feet.
