Find The Area Of A Right Triangle : Example Question #1

A right triangle has a total perimeter of 12, and the length of its hypotenuse is 5. What is the area of this triangle?

Possible Answers:

10

12

6

15

3

Correct answer:

6

Explanation:

The area of a triangle is denoted by the equation 1/2 b x h.

 

b stands for the length of the base, and h stands for the height.

 

Here we are told that the perimeter (total length of all three sides) is 12, and the hypotenuse (the side that is neither the height nor the base) is 5 units long.

 

So, 12-5 = 7 for the total perimeter of the base and height.

 

7 does not divide cleanly by two, but it does break down into 3 and 4,

and 1/2 (3x4) yields 6.

 

Another way to solve this would be if you recall your rules for right triangles, one of the very basic ones is the 3,4,5 triangle, which is exactly what we have here
