Answer:
B. 80.2 square inches
Step-by-step explanation:
This figure is a composite figure made up of two rectangles (see attachment).
The area of a rectangle is denoted by: A = lw, where l is the length and w is the width.
In the top rectangle, the length is 3 and the width is 10.2, so A = 3 * 10.2 = 30.6 square inches.
The length of the bottom rectangle is 8 and the width is 6.2, so the area is A = 8 * 6.2 = 49.6 square inches.
Add these together: 30.6 + 49.6 = 80.2 square inches.

C= the price of a cheeseburger and l = the price of a lemonade:
Divide the second equation by -2 to begin the process of solving by elimination:
Now that we have c, 4, we can plug it in to one of the equations to find l:
So, each cheeseburger is $4 and each lemonade is $1. The final answer is:
1 cheeseburger and 2 cups of lemonade would cost $6.
