Question

Find the perimeter of the image below:
32.1 units
35. 8 units
37.6 units
39.2 units

Answer 1

So we pretty much just need to use the distance formula a bunch of times to find out the lengths of each side

Distance formula \(\large \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\)

Example: the length from B to C is \(\large \sqrt{(4 - (-4))^2 + (10 - 5)^2} = \sqrt{89} = 9.4 \)

And just do that repeatedly for the other distances
