## shaniehh one year ago Find the perimeter of the image below: 32.1 units 35. 8 units 37.6 units 39.2 units

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
