George makes a 25 scale drawing of a triangular sail. The triangle in his drawing is 2 feet high with a base of 1 foot. What is the area of the sail?
Since the scale of the drawing is 1:25, the actual dimensions of the sail are 25 times larger than those in the drawing.
Therefore, the actual height of the sail is 2 feet x 25 = 50 feet, and the actual base is 1 foot x 25 = 25 feet.
The area of a triangle is calculated using the formula: (base x height) / 2
So the area of the actual sail is (25 feet x 50 feet) / 2 = 625 square feet.
