A triangle has a base x and an altitude y. A second triangle has a base twice the altitude of the first triangle, and an altitude twice the base of the first triangle. What is the area of the second triangle?

A 2xy
B 0.5xy
C 0.66xy
D 4xy

Correct Answer: 2xy

a triangle has a base x and an altitude y   A second triangle has a base twice the altitude of the first triangle = 2x and an altitude twice the base of the first triangle = 2y ∴Area of 2nd triangle = (1/2)(2x)(2y) = 2xy  ans: 2xy
