The area of a triangle is base * height / 2
The length of the base is 16 - 12 = 4
The height is 31 - 0 =0
Then the area is 4*31/2 = 62
Given:
The equation is

To find:
The reason for second step.
Solution:
We have,

Using multiplication property of equality, multiply both sides by 3.

Using addition property of equality, add 4 on both sides.


Using division property of equality, divide both sides by 2.


So, the reason for second step is multiplication property (=).
Therefore, the correct option is D.
