Answer to Problem 14CR
Explanation of Solution
Given information: a college has 1500 feet of boards to form three adjacent outdoor ice rinks.
And the structure of three adjacent outdoor ice rinks is as follows-
According to the figure total length of boards that will be used in 1 outdoor ice rink is =
Since there are three adjacent outdoor ice rinks, then the length of boards that will be used =
Now according to question, total length of boards = 1500 feet
Now according to figure area enclosed by 1 outdoor ice rink =
Since there are three adjacent outdoor ice rinks, then the total area enclosed is =
Let the total area enclosed be A
Putting
Thus the dimension for the maximum surface area for the ice surface is,
