Problema Solution
A rectangular pool is 30 feet wide and 40 feet long. It is surrounded on all four sides by a wooden deck that is x feet wide. The total area enclosed within the perimeter of the deck is 3000 square feet. What is the width of the deck?
Answer provided by our tutors
x = the width of the deck, x>=0
the total area is = (width + 2x)*(length + 2x)
(30 + 2x)(40 + 2x) = 3000
by solving we find:
x = 10 ft
