Answer:
Step-by-step explanation:
The area of a triangle is related to the base and height by ...
A = 1/2bh
Filling in the given information, we can find the base from ...
199.5 = (1/2)(b)(b+2)
399 = b^2 +2b . . . . multiply by 2
400 = (b +1)^2 . . . . add 1 to complete the square
20 = b +1 . . . . . . . . take the positive square root
19 = b . . . . . . . . . . . subtract 1
h = b+2 = 21
The base of the triangle is 19 feet and the height is 21 feet.
Answer: D) w = 9 feet
Work Shown:
That points us to the final answer choice D.
