Well, since there is no image I thought I would provide what a rectangle would probably look like in your case. The rectangle can be split into half parts 4 ways.
<h2><em><u>Ways it can be Split:</u></em></h2>1. We can split it the hotdog way, or staright down the rectangle (drawing provided down below)
2. We can split it the Hamburger way, again drawing is provided.
3. We can split it from the top-left corner to the bottom-right, and the opposite way around.
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.
Hope this helped!
