To find the length of the unknown leg of the triangle, we will need to use the Pythagorean Theorem.

Pythagorean Theorem: a^2 + b^2 = c^2

---a and b are the legs of the triangle

---c is the hypotenuse

a = 2

b = ?

c = 3

2^2 + b^2 = 3^2

4 + b^2 = 9

b^2 = 5

b = 2.236

b (rounded) = 2.2

Answer: 2.2 ft

Hope this helps!
