The sides of right triangle ABC are such that the length of side AB is greater than the length of side BC, which itself is greater than the length of side AC. If side AB = 143 and side AC = 55, what is the area of the triangle?

A. 3113
B. 3224
C. 3432
D. 3630
E. 7260

Given that AB>BC>AC. So, AB is the hypotenuse of the triangle.

$$BC=\sqrt{143^2-55^2}=\sqrt{(11*13)^2-(11*5)^2}=11\sqrt{13^2-5^2}=11*12$$.

The area = 1/2*BC*AC = 1/2*(11*12)*55 = 66*55 = 3630.

Bunuel's solution is exactly how I would have answered this question.
However, if I had no idea how to answer the question (or if I had only 10 seconds remaining), I still would have guessed D.

Here's why:
Notice that E (7260) is twice as big as D (3630).
Since area of a triangle = ONE-HALF times base times height, answer choice E is a good distractor for people who forget to HALVE the product of the base and height.
So, I'd GUESS D.

Cheers,
Brent
