Answer:
I think the answer is 7200
Step-by-step explanation:
10*6*12*10=7200. I did that because you find volume by multiplying Base*With*Height. I don't think that the 8cm on top does anything to help you solve this question. Sorry if I'm wrong!
Identify the length of both bases. The bases are the two Identify parallel sides of the trapezoid.
12 and 6 are our bases.
...Add the lengths of the bases.
12+6 = 18
..Multiply the sum of the lengths of the bases by the height. ...Divide the result by two.
18×5= 90
90÷2= 45
The area is 45.

Step-by-step explanation:
Answer:
200 inches of ribbon
Step-by-step explanation:
if the formula to finding an area is s²
and we already know that the area is 400, so we divide the area by 1/2 to get the length of each side
