The answer is 7.3. Hope that helps.
Answer:
640.5 cm^2
Step-by-step explanation:
So the formula for trapezoid is height times the average of the bases. So 25+36=61, and then we divide that by 2 to get 30.5 as our average. Then, we take 30.5 and multiply it by 21 and we get 640.5.
You can use addition to solve this problem. 7+_= 15
I believe 26 units is the correct answer because you basically gotta multiply top from bottom
