Question

If the width of the flower bed is 15 feet, what is its length? Write your answer as an evaluation of a function.

Answer 1

L=2.5

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.
