The mean = sum of all the measurements / number of measurements (n)
= (5 + 3 + 3 + 8 + 8) / 5
= 27 / 5
= 5.4 Answer
Because we know the leg with the measure is not the hypotenuse, the two legs would be 5 inches each. Using the Pythagorean Theorem, 5^2 + 5^2 = C^2, when C is the length of the hypotenuse. 5^2 is 25, so 25 + 25 = 50. We need to find the square root of 50, and the closest number is 7.07 or 7.1.
Missing info: The width of the patio is 3/4 its length.
Given:
Area = 432 square feet.
length = x
width = 3/4 * x
Area of a rectangle = Length * width
432 ft² = x * 3/4 * x
432 ft²/3/4 = x²
432 ft² * 4/3 = x²
576 = x²
√576 = √x²
24 = x
Length is 24 ft.
Width = 3/4 * 24ft
Width = (3*24)/4
Width = 72/4
Width = 18 ft.
