Answer:
Area = 12
Step-by-step explanation:
The perpendicular bisector of the triangle going from upper left to the middle marks the height of the triangle. It's area is found from the standard formula.
Area = b * h / 2
b = 2 + 2 = 4
h = 8
Area = 1/2 * 4 * 8
Area = 1/2 * 32
Area = 16
The smaller triangle is found from all the twos.
b = 2 + 2 same as the larger triangle
h = 2
Area = 1/2 2 * 4
Area = 1/2 8
Area = 4
Total Area = 4 + 16
Total Area = 20
Answer:
yes
Step-by-step explanation:
3 * 10 (m) = 30 so 30 - 6 = 24. 3(10) - 6 is basically the same thing just written different, so it equals 24 too. 3(4) just means 3 times 4 ,which equals 13. Hope that made sense lol

Yes, to make it simpler and easier to tell, you could put both these fractions into decimals or percentages.
4/6 as a decimal would be .66 or 66%
4/7 as a decimal would be .57 or 57%

Answer:
1041.27
Step-by-step explanation:
A=πrl+πr2
l=r2+h2
Solving forA
A=πr(r+h2+r2)=π·12·(12+102+122)≈1041.26829
