(URGENT) need answer for today

To find perimeter you must add all the side lengths together:

P = AB + BC + AC

The side lengths AC and BC are easy to find. You must simply count how many units they span. Please refer to the image below to see how I did this.

To find the length of AB is a bit trickier. Since the trianlge shown is a right trianlge you may use pythagorean theorem

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = 6

b = 7

^^^Plug these numbers into the theorem

solve for c

36 + 49 =

= 85

c ≈ 9.219

c ≈ 9.2 units

Hope this helped! Let me know if you have any further questions!
