GRE Quantitative Reasoning › How to find if right triangles are similar
Quantitative Comparison
Quantity A: The area of a triangle with a perimeter of 34
Quantity B: 30
Quantity A is greater.
Quantity B is greater.
The two quantities are equal.
The relationship cannot be determined from the information given.
A triangle with a fixed perimeter does not have to have a fixed area. For example, a triangle with sides 3, 4, and 5 has a perimeter of 12 and an area of 6. A triangle with sides 4, 4, and 4 also has a perimeter of 12 but not an area of 6. Thus the answer cannot be determined.
