Since c=15 and d=3, we replace the c and d variables with 15 and 3.
0.5x15-1.7x3
0.5x15=7.5
1.7x3=5.1
Now subtract.
7.5-5.1=2.4

The equation for the area of a triangle is A= b*h /2. So, plug in your known variables, and you get 270in^2= b*30 /2. First you multiply by 2 to cancel out the division for 2, which gets you 540= b* 30. To get "b" by itself, divide both sides by 30, giving you <u>18=b</u>.
To check this, plug in your new known variable, as 270= 18* 30 /2. This will equal as 270=270, confirming 18in as the correct measurement.
The answer is c. 
a. 
(2.2≠5.11) (2.2 is not equal to 5.11)
b. 
or 0.625 (0.625≠5.11) (0.625 is not equal to 5.11)
c. 
(5.11=5.11) (5.11 is equal to 5.11)
Therefore c is the answer
