What is the area of a triangle with base = 12 in. and height = 6 in.?
a. 144 in.2
b. 72 in.2
c. 36 in.2
d. 18 in.2

The answer is  C. 32 inches squared

How to Solve:

Multiply 12 by 6 and then divide it by 2
 
12 multiplied by 6 equals 72 
72 divided by 2 equals 36 therefore the answer is 36 inches squared.

The area of a triangle is:

A=bh/2, b=base length and h=height, we are told that b=12 and h=6 so

A=(12*6)/2 in^2

A=36 in^2
