Applying it's formula, the area of the given triangle is of 30 centimeters squared, that is, 30 cm².

<h3>What is the area of a triangle?</h3>

The area of a triangle of base b and height h is given by half the multiplication of these measures, that is:

A = 0.5bh.

In this problem, we have that b = 12 cm, h = 5 cm, hence:

A = 0.5 x 12 cm x 5 cm = 30 cm².

⇒Associative property of Addition is applied for three real numbers.For, any three real numbers, A, B and C
≡A+B+C=A+(B+C)=(A+B)+C=(A+C)+B→→→Associative Property of Addition
that is , we can add any two numbers first and then the third number with them.
⇒Also, Commutative Property of Addition of two numbers says that for any two numbers , A and B
≡A+B=B+A
We have to find equivalent expression using Associative Property of the sum of set of three numbers
