Question

What is the perimeter

Answer 1

Answer:

The answer to your question is:  letter D

Step-by-step explanation:

First we need to find the distances between the points,

distance AB = 8       get it just by counting the points in the graph

distance AC = 9       get it just by counting the points in the graph

To know the distance BC, use the pythagorean theorem

         c2 = a2 +b2

         c2 = 8² + 9²

         c² = 64 + 81

          c² = 145

         c = 12.04

Finally, perimeter = AB + AC + BC

                              = 8 + 9 + 12.04

                               = 29.04 units

Answer 2

Answer:

D: 29.04

Step-by-step explanation:

AB = 7.5

AC = 7.5

P= 2x(LxB)

P= 2x(7.5+7.5)

P=2x15

P=30

Ans D is the closest.
