Answer:

Step-by-step explanation:
Note that the squares are on the sides of these triangles are on the hypotenuse/one leg.
We know that the area of a square is
where l is the length. Since we know the area, we can find the square root of the area to find the side length.
So the side lengths are
and
.
Since we know the hypotenuse is
and one of the legs is
, we can use the Pythagorean Theorem to find the missing side.
The Pythagorean Theorem states that
, where c is the hypotenuse and a/b are the legs.
We know the <em>hypotenuse </em>and <em>a leg</em>, so we can substitute inside

Squaring a square root is the same as doing nothing.

Answer:
20.4
Step-by-step explanation:
11/8 = x / 3
cross multiply
8x = 11 * 3
