First, take three off it, because that will form the whole-number part:
3.92 = 3 + 0.92
Next, read off the place value of the last digit. The 2 is in the 'hundredths' column, which means that 0.92 = 92/100:
3.92 = 3 + 92/100
Finally, simplify 92/100 by dividing top and bottom by 4 to get 23/25. Then, shove it all together:
3.92 = 3 23/25
The area of the triangle will then be 9 times as great.
The formula of the area of a triangle is 1/2bh, so if the base has been tripled and the height has been tripled, you're essentially multiplying 3 to the original equation twice (3 x 3 = 9).

Explanation:</h2>
Here we have the following expression:
And the question asks for solving the equation for the variable 
. So we need to divide both sides of the equation by 
:
