Question 498170: A rectangular porch has a perimeter of 49 ft and a width of 6.5 ft. what is the length of the porch in feet.
Answer by texttutoring(324)   (Show Source):
You can put this solution on YOUR website! We know that the formula for the perimeter of a rectangle is:
P = 2L + 2W
In this question, we are given the values for perimeter, P, and the width, W. We can substitute these values into the equation and solve for L:
P = 2L + 2W
49 = 2L + 2(6.5)
49 = 2L + 13
49 - 13 = 2L
36 = 2L
36/2 = L
L = 18
The length of the porch is 18 feet. Hope this helps!
