Area of trapezoid = 1/2(b1 +b2) h
Where b1 = 6 cm , b2 = 20 cm and h = 10 cm
A = 1/2(6 + 20)(10)
A = 1/2 (26) (10)
A = 130
Answer
A = 130 cm^2
Hope it helps.

Answer: 210</h3>
===========================================================
Explanation:
There are 7 unique letters in the word HEXAGON.
For the first slot, we have 7 choices. Then the next slot has 6 choices. Then the third slot has 5 choices. We count down by one each time we need to fill another slot.
Multiply out the values mentioned: 7*6*5 = 42*5 = 210
----------------
Alternatively, you can use the nPr permutation formula with n = 7 and r = 3.

We have the "7*6*5" show up again after the "4*3*2*1" portions cancel.
210 = 100%
260 = x%
260*100/210=123.8%
x=123.8%
123.8% - 100% = 23.8%
The answer is 23.8%
Ok, First step you need to is change 21 to 22 then you estimate 12 which will give you 10 then multiply 22x10 which will give you 220. Hope this helped!
yes -9 is an integer because it is a number
