Step-by-step explanation:
The perfect squares from 1-30 are:
1, 4, 9, 16, 25
Total no. of perfect squares = five =5
Total no. of non perfect squares = 30-5 = 25
Ratio = = 5 / 25 =
Let x represent the length in feet of the area along the barn wall. Then the width of the area (out from the wall) will be 450/x, and the total cost of fence will be
cost = 5*(x +2*450/x)
A graphing calculator shows the minimum of the cost function is where x=30.
In order to minimize the cost of fencing, the fourth side should be 30 ft long.
cost = 5*(x +2*450/x)
