3. i can barley see the second picture but i believe the answer is 123 inches squared. (i dont know if i did this one right, I'm a I D I O T.)
Step-by-step explanation:
1. You would multiply 6 by 2.4 which equals 14.40.
2. you would multiply all sides (that are available.) then subtract the non-shaded square which give you a total of 128cm².
3. you would multiply all sides, 24 x 24 x 36 = 20.736, (you add the decimal for farther progress.) round by the nearest tenth you get 207 then add the right triangle area and you get 123 inches squared.
I HOPE YOU GET THIS RIGHT! HAPPY EARLY VALENTINES DAY!
