Help. I need an 80 in math by Friday, brainliest if you can help.
ehidna [41]

Answer:

26

Step-by-step explanation:

To find the area of the three combined shapes, multiply the length times the width of each and add them together. Five times two is 10, and since there are two identical rectangles (the top and the bottom one), the current combined area is 20. Three times two is 6. 20 + 6 = 26.
