Answer:

The hypotenuse is about 13.892 feet

The entire length is about 32.892 feet

Explanation:

First, we have to use the Pythagorean Theorem to find the hypotenuse. The Pythagorean Theorem is:


a^(2) + b^(2) = c^(2)\\

Plug in the values...


7^2 + 12^2 = c^2

Simplify the exponents...

49 + 144 =
c^2

Now we add.

193 =
c^2

To remove the exponent from c, lets take the square root of it.


√(193) = √(c^2)

Which is almost 13.892 feet.

Now to find the perimeter of the entire triangle, lets add up all of the sides.

12 + 7 + 13.892 is roughly 32.892 feet. Hope this helps you!
