This is a subset of solutions for the assignment Modular Programming with Squares. This is just one way of coding the solutions, there are multiple correct solutions for the same.

2. The above square needs to be divided into two equal parts. You can do this with a horizontal or vertical line across the middle or divide the square along the diagonal. The solution below divides the cake along the horizontal line

across the middle.

3. The square now needs to be divided into quarters. Two possible solutions, along the diagonals or using horizontal & vertical lines. The solution below divides the cake along the horizontal & vertical lines.

5. You need to divide the 12 x 12 cake into 9 equal pieces in this case. Each slice is going to be 4cm x 4 cm. Here is a solution using Nested Loops.

### Building Up with Squares as the Basic Building Blocks

1. The square can be drawn using the code:

2. Here is the code for the rectangle drawn without using Nested Loops:

3. As seen from the code above, there is a repeating pattern. After drawing each square, you need to move to the starting position for the next square. The above code can be rewritten using Nested Loops as:

4. & 5. To draw the large square that is double the size of the small square, different techniques can be employed. The easiest is to start from the midpoint of the figure. Each time, draw the small square and then turn 90 degrees to the right. Here is the code that uses Nested Loops.

Rt // Here, you want to try and get to the midpoint of the large square

Fd 3 // 3 cm from the top of the rectangle to the midpoint of large square
