Question

It's asking me what figure 20 would look like based off of these 3 figures, the perimeter, area and the equation. I've done many problems like this but that was all over a year ago and im stuck

Answer 1

Figure 20 would have 60 squares on the base, 60 squares height

Perimeter = 60 + 60 + 60 + 20 + 40 + 20 + 40 + 20 = 320 ==> Perimeter = 320

Area = seven times 20 by 20 = 7 (20 x 20) = 7 (400) = 2800 ==> Area = 2800

Equation: Number of squares = 7 n^2, where n is the number of the figure

Equation: Number of squares = 7 n^2
