Area 2

From Homeworkwiki

The sail of a boat is shaped like a right triangle. The area of the sail is 150 square feet and the base is 15 feet. Find the height of the sail?
Solution: Area of a right triangle = (1/2) x base x height
Therefore, 150 = (1/2) x 15 x height
Implies, height = (2 x 150)/15 = 300/15 = 20 feet.
