Question

Write the method drawSquare below.

Precondition: 0 ≤ x < 10, 0 < y ≤ 10, and len > 0. Draws a square on a 10-by-10 xy-coordinate grid and prints the square’s side length and area.

Answer 1

To draw a square on a 10-by-10 xy-coordinate grid and print the square’s side length and area, you can use the drawSquare method. This method takes the x and y coordinates, as well as the length of the square as parameters.

Step-by-step explanation:

To draw a square on a 10-by-10 xy-coordinate grid and print the square’s side length and area, you can use the following method:

1. Define the method as drawSquare with the parameters x, y, and len.
2. Check if the precondition is satisfied, i.e., if 0 ≤ x < 10, 0 < y ≤ 10, and len > 0.
3. Print the square’s side length using len.
4. Calculate the square’s area by multiplying the side length (len) by itself.
5. Print the square’s area.

For example, if you call the method as drawSquare(5, 3, 4), it will draw a square at coordinate (5, 3) with a side length of 4 and print:
Side Length: 4
Area: 16
