What is the area of a triangle with the following vertices L(2, 3), M(5, 1), and N(3, 5) ? Choose the correct answer:
A) 3	B) 4	C) 5	D) 6	E) 7

Rationale: there is a direct formula to calculate the are of a triangle based on coordinates of its vertices and one could use it to solve this problem . though if you make a diagram minimum simple calculations will be needed : answer : b .
Answer: B
