Answer:
4 ft
Explanation:
Since the shape is a square, the bottom part of the orange triangle would be equal to half of a side or 6/2, 3. Now, we can use the pythagorean theorem to find the height:
a^2 + b^2 = c^2
We are already given the hypotenuse or c as 5. We are also given a leg or a, as 3. We can plug those numbers in:
3^2 + b^2 = 5^2
9 + b^2 = 25
b^2 = 16
b = 4 ft
