we have

Applying the Pythagorean Theorem
Find the length side b




Area of triangle

step 2
Find the area of the square
The area of the square is

we have

substitute

step 3
Find the total area of the figure
Adds the areas

D.
This is because it is a question that involves doing actual math rather than just asking and getting an answer.
Step-by-step explanation:
First, you divide the numerator and the denominator by 14. (Your fraction is 14 over $2.99.
Once you have that number, you need to simplify.
You get the number 1 over 0.2125 which can be rounded to 0.21. That being said, the unit rate would be be 1 : 0.21.
