Answer:
Side length = 12 feet
Hypotenuse = 13 feet
Step-by-step explanation:
Area of a triangle is: A = (1/2)base * height
so,
30 = (1/2)5 * height
30 = 2.5 * height, divide by 2.5 from both sides
12 = height
Pythagorean theorem is a^2 + b^2 = c^2, where c is the hypotenuse
so,
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2, square root both sides
c = 13
