Given a right triangle (ABC) with side a = 30.30 ft and side b = 20.20 ft, what is the length of the hypotenuse c?
  1. 3.64 ft
  2. 36.41 ft
  3. 364.16 ft
  4. 3641.62 ft
Explanation
Answer: B - The length of the hypotenuse c is 36.41 ft.

Solution

Use right triangle formula c2 = a2 + b2

Where a = 30.30 ft
b = 20.20 ft

c2 = (30.30 ft)2 + (20.20 ft)2 = 918.10 ft2 + 408.04 ft2 = 1,326.14 ft2

c = (1,326.14 ft2) ½ = 36.41 ft
