a) Polynomial equation that represents total area can be written as,
as per figure,
dimension are as follows,
Length = , Breadth =
∴ Area = Length x Breadth = x
So we get equation as,
=
b) Total area of flower bed when width of border is 1.5 feet
width of border is value of x
∴ x = 1.5 feet
by substituting value of x in equation we get,
Total area = 9 + 33 + 30 = 72 feet
