The function used to determine the area of the second garden is expressed as
g(n) = 5n^2
where n represents the width of the second garden
The garden is inside a square whose length is 100. Recall, all sides of a square are equal. If the sides of the garden are parallel to the sides of the square, then the maximum length of each side of the garden is 100
To find the largest possible area of the second garden, we would substitute n = 100 into the function. We have
g(100) = 5(100)^2 = 5 x 10000 = 50000
