The equation for a square is base x height. It's a square so you know the length along the bottom/top and the length on all sides. Just multiply the length of the bottom and one side and round to two digits past the decimal. So if a square had a side of 2, the area is 2x2=4

If it had a side of 2.1 you would multiply 2.1 x 2.1 = 4.2 sq/ft

thank you for the help so the answer would be 4.2

Your square is bigger. It has a side of 6.25. Do you have a calculator?
anonymous
  • anonymous
yes i do
anonymous
  • anonymous
Ok, so what is the length of the bottom of the square?
anonymous
  • anonymous
and multiply by the length of the side. Hint...They are the same.
anonymous
  • anonymous
25 i think
anonymous
  • anonymous
Nope.
anonymous
  • anonymous
ok tell me what im doing wrong 6.25x4x4=100
anonymous
  • anonymous
The length of the base is 6.25, and the height is 6.25. You only have to multiply one side by the other side.

oh i was confused ok so heres my answer 39.0625
anonymous
  • anonymous
That's good, now it says to round to significant digits, right?
anonymous
  • anonymous
The original question gave you a measurement that was two places past the decimal.
anonymous
  • anonymous
yes sir
anonymous
  • anonymous
so that would be 40
anonymous
  • anonymous
So, make sure your answer is rounded two places past the decimal.
anonymous
  • anonymous
39.0625 rounds to what two places after the decimal? 39.??
anonymous
  • anonymous
sothat would be4000
anonymous
  • anonymous
Nope.
anonymous
  • anonymous
You have an answer that has four numbers after the . Right? 39.0625
anonymous
  • anonymous
im sorry im confused
anonymous
  • anonymous
When you are told to round answers to significant digits your answer will have just as many numbers past the . as the number you put in.
anonymous
  • anonymous
give me one second
anonymous
  • anonymous
6.25 has how many numbers after the decimal?
anonymous
  • anonymous
2
anonymous
  • anonymous
Good, so your answer has four. Correct?
anonymous
  • anonymous
When you are told to round to significant digits. You have to round your answer so it has just as many numbers after the decimal as the original number. 6.25 has two numbers after the decimal, your answer needs to look the same and have only two numbers.
anonymous
  • anonymous
four numbers or four past the decimal
anonymous
  • anonymous
So, you have 39.0625 and you want to give an answer that has only two numbers after the decimal. Look at the third number (2) and round up or down. In this case round down and then give answer as: 39.06
anonymous
  • anonymous
oh so your supposed to round down thats where i was confused
anonymous
  • anonymous
If the answer had been 39.065 you would have rounded up to 39.07 and that would have been the correct answer.
anonymous
  • anonymous
i was rounding 39 to 40 sorry about that
anonymous
  • anonymous
No, problem. If you don't know what else to do, try to make you answer as accurate as the question. Match all the number places past the decimal in your answer as they gave you in the question.
anonymous
  • anonymous
If your answer has extra places, round them off.
anonymous
  • anonymous
alright thanks im in 9th grade and algebra is hard thankyough i really appreciate it
anonymous
  • anonymous
did you get it wrong @hicks
anonymous
  • anonymous
