Problema Solution
A rectangular garden is 12 ftx16 t is surrounding by a walkway which is a uniform width. If the walkway has an area of 165ft squared, what is the width of the walkway?
Answer provided by our tutors
let 'x' represent the width of the walkway in feet
area = length * width
to find the area of the walkway, we subtract out the area of the garden:
area of the garden = 12*16
area of the walkway = (12+w)(16+w) - 12*16
165 = (12+w)(16+w) - 12*16
solving for 'w' we have a positive value of w=5
the width of the walkway is 5 ft
