Question 63754
The greenhouse I am building for my wife is 6 feet longer than it is wide. Write an algebraic expression for the perimeter if the length is expressed as X. If X equals 20, what is the perimeter?
---------------------
length = x = 20
width = x-6= 14
Perimeter = 2*length + 2*width
Perimeter = 2*20 + 2*14=40+28=68 feet
