Answer:
L = 17 m W = 12 m
Step-by-step explanation:
Here is the answer.
Given expression is
.
where 
Now we have to simplify this and find the next step so that negative exponent gets eliminated.
We know that when negative exponent changes sign, then it moves from numerator to denominator or from denominator to numerator as shown in the formula:

or
n has negative exponent in denominator so it will move to numerator and we get:

or 
Hence final answer is
.
Triangle EDC is similar to Triangle CBF by angle angle. Angle B is congruent to angle D because in a parallelogram opposite angles are congruent. Angle BFC is congruent to angle ECD because parallel lines imply alternate interior angles are congruent. FC=7 DC=16 2/3 EC=10
I’m going to assume you know slope-intercept form. The work will be displayed below on my magnificent, college-ruled paper.
