Without knowing the formula for determining the area of a triangle, a student investigated and determined a way to find the area. He tried several options, but decided to construct a rectangle by erecting parallel sides at right angles at each end of the general triangle. Examine his drawing. Which conclusion is correct? 
A. The constructed rectangle length is the same as the base of the triangle. No conclusion for area value. B. The constructed rectangle has an area twice the area of the triangle. To find the area of a triangle, multiply one-half the base times the height. C. The constructed rectangle is half the area of the triangle. To find the area of a triangle, multiply the base times the height and double. D. The constructed rectangle is the same area as the triangle. To find the area of a triangle, multiply the base times the height.
