answer is C. 252 ft^2
split the figure into two pieces and first figure out the rectangle (shown in turquoise).
If you multiply the width and length (18*6) you should get 108.
Then figure out the trapezoid (in magenta). the formula is (a+b)/2*h where a and b are the bases and h is the height. the bases are given, 6 and 18. to find the height, subtract the entire figure's height by 6, which is 18-6 and gives us 12. so the formula converted to this problem is (6+18)/2*12. simplify parenthesis and get 24/2*12. 24/2=12, so multiply 12*12. The area of the trapezoid is 144. Add the areas of both figures together and get 252.

Step-by-step explanation:
There is a rule for logarithms that says:
.
This is actually called quotient rule and it's name is based off the right hand side of the equation there.
So you have that you can write your right hand side as:
.
So your equation is:
Now let's write this in the equivalent exponential notation:
So the value of the given fraction is .
Note! In general, the equivalent exponential form of is
.
