Question

A square has a side of 6.25 feet. What is the area in square feet? Round to the correct significant digits

Answer 1

Do you know the formula for area of a square?

Answer 2

@gypsy1274 nope..

Answer 3

Length times width.
Since a square has 4 sides of the same length, side times side or side squared also works.

Answer 4

@gypsy1274 so would it be 39.0625; then round it so.. 39.1?

Answer 5

I'm not familiar with the significant digits, I think it would mean to round to two digits since the original measurement is given to two digits.

Answer 6

@uri Can you answer this question about significant digits?

For multiplication and division, the result should have as many significant figures as the measured number with the smallest number of significant figures.

so nearest hundredth aka .01

Answer 8

39.06 we rounded to the nearest hundredth. Wait for second opinion tho.
