Problema Solution
bob wants to fence in a rectangle garden in his yard. he has 72 feet of fencing to work with and wants to use it all. if the garden is to be x feet wide, express the area if the garden as a function x.
Answer provided by our tutors
If the width is x then:
2x + 2*length = 72
length = (1/2)(72 - 2x)
length = 36 - x
A = the area
A = width*length
A = x*(36 - x)
A = 36x - x^2
The area of the garden as a function of is 36x - x^2.
