Exercise 1 of 3:

Assume you want to build a farm house. You are getting three offers to buy land. The three pieces of land look as follows (measurements in yards):

Land 1 has a cost of $100 per square foot.

Land 2 has a cost of $125 per square foot.

Land 3 has a cost of $142 per square foot.

Calculate the costs to buy each land and print them in the console. (watch out, the measurements on the plan are in yards, while the given prices are per square foot!)

Exercise 2 of 3:

In mathematics, the Fibonacci numbers are the numbers in an integer sequence, called the Fibonacci sequence, and are characterized by the fact that every number after the first two is the sum of the two preceding ones:

The value of each number can also be expressed as:

Write a program that calculates the first 20 Fibonacci numbers and prints them to console. Then, of those twenty numbers, print only those numbers to console again, which are also prime numbers.

Exercise 3 of 3:

Using nested loops, write a program the prints the following patterns to console:

1z0 70 Land 1 30 50 100 120 40 50 50 70 50 Land 3 50 10 Land 2 20
