Answer:

10 units

Step-by-step explanation:

We can find the length of the hypotenuse of this right triangle using the Pythagorean theorem.

AB² = AC² +BC²

AB² = 2² +4² = 20

AB = √20 ≈ 4.47

Then the perimeter is ...

P = AB +BC +CA = 4.47 +4 +2 = 10.47

P ≈ 10 units

What is the perimeter of the figure?

Monica [59]

Hey there,

So when finding the perimeter, we do addition.

So . . .

20 + 12 + 18 + 7+ 13+6

Your correct answer would be 76

Hope this helps.
