You are writing a program that will take as input a home type, a length, and a width.

Home types are: "trailer", "bungalow", "two-storey"

Home type: bungalow

Lengths are from 20 feet to 72 feet (real estate still tends to use imperial measures)

Length:  48

Widths are from 8 feet to 27 feet

Width:  27

From this, you are to generate an insurance report (example printed line):

You are insuring a bungalow of 1296 square feet.

If any of the data is invalid (less than the minimum or maximum, or not one of the defined types) then you should print:

***INVALID DATA***

Note, however, if you are dealing with a trailer, you have to also check the following:

If the trailer is 40 feet in length or less, you are insuring it as a travel trailer, so your output might look like:

You are insuring a travel trailer of 320 square feet.

If it is more than 40 feet in length, it will look like this:

You are insuring a mobile home of 1152 square feet.

Remember, a two-storey has double the square feet.

You should employ a nested if structure to solve this problem.
