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

anonymous · Answer

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

anonymous · Answer

thank you for the help so the answer would be 4.2

anonymous · Answer

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 · Answer

That's good, now it says to round to significant digits, right?

anonymous · Answer

The original question gave you a measurement that was two places past the decimal.

anonymous · Answer

yes sir

anonymous · Answer

so that would be 40

So, make sure your answer is rounded two places past the decimal.

anonymous · Answer

im sorry im confused

anonymous · Answer

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 · Answer

give me one second

anonymous · Answer

6.25 has how many numbers after the decimal?

anonymous · Answer

2

anonymous · Answer

Good, so your answer has four. Correct?

anonymous · Answer

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 · Answer

four numbers or four past the decimal

anonymous · Answer

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 · Answer

oh so your supposed to round down thats where i was confused

anonymous · Answer

If the answer had been 39.065 you would have rounded up to 39.07 and that would have been the correct answer.

anonymous · Answer

i was rounding 39 to 40 sorry about that

anonymous · Answer

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 · Answer

If your answer has extra places, round them off.
