a. Since the shapes are all squares, the perimeter of the squares are 4s where ss is the side length and the areas are \(\displaystyle{s}^{{{2}}}\) where s is the side length. The spreadsheet is then completed as

b. B4 is the perimeter for a side of 1.5. Since the perimeter is 4 times the side length and the side length is in cell A4, the formula will be \(\displaystyle={4}\times{A}{4}\).

c. C4 is the area for a side of 1.5. Since the area is the square of the side length and the side length is in cell A4, the formula will be \(\displaystyle={A}{4}\wedge{2}\).

d. Plot the points (side, perimeter) from the spreadsheet and then connect the points with a line:

Plot the points (side, area) from the spreadsheet and then connect the points with a smooth curve:
