Answer:
9
Step-by-step explanation:
Area of a triangle=(base*height)/2
1) Input the values
54=(12h)/2
2) Multiply both sides by 2
54*2=(12h/2)2
108=12h
3) Divide both sides by 12
108/12=12h/12
9=h

To find the percent of 15 out of 60, you have to divide fifteen by sixty.
Then, you multiply your answer by 100. (We do this because 100 percent is a exact amount. 100% of sixty is...well, sixty.)
15 / 60 = 0.25
Now, we can multiply 0.25 by 100:
0.25 * 100 = 25 (basically just moving the decimal two places to the right.)
Next, add a percent sign:
25%, is your answer.
15 is 25% of 60.
