Hi

Step-by-step explanation:

It's 20 because you round

Answer 2

Answer:

Below

Step-by-step explanation:

First we can find the length of the two sides that are NOT the hypotenuse :

    Counting side AC we can see that AC = 8cm

    Counting side BA we can see that BA = 4cm

Now to find the angular side aka the hypotenuse we have to use Pythagorean theorem :

     a^2 + b^2 = c^2

Plugging in our values :

     (8)^2 + (4)^2 = c^2

     64 + 16 = c^2

             80 = c^2

Now we have to square this number to get the value of c

         √ 80 = c

            8.9 = c

Adding all the values up to get the perimeter :

     8.9 + 8 + 4 = 20.9 cm

Hope this helps! Best of luck <3
