What’s the perimeter rounded to the nearest tenth of (-4,4) (0,4) (3,6) (4,4) (-2,4) (0,-2)

Answer 1

24.2 = the perimeter

4 + 2sqr52 +sqr5 + sqr13

=4+5sqr13 +sqr5

= about 4+18+ 2.2 = 24.2

draw a rough sketch or graph. Plot the points

then construct 4 right triangles and use the Pythagorean Theorem for each triangle. then sum the 4 hypotenuses plus 4 (the distance from (-4,4) to (0,4))
