Problema Solution
the perimeter of my new swimming pool is 52ft. the length of the pool is two more than triple th e width. what are the length, width, and area of the pool?
Answer provided by our tutors
We will consider rectangular swimming pool.
Let
'l' = the length of the swimming pool
'w' = the width of the swimming pool
A = w*l the area of the rectangular swimming pool.
P = 2(w+l) the perimeter of the pool
2*(l+w) = 52
l = 2 + 3*w
By solving this system of equations we find
l = 20 ft
w = 6 ft
A = 20*6 = 120 ft^2
the length is 20 ft.
the width is 6 ft.
the area is 120 ft^2.
