A square has a side of 6.25 feet. What is the area in square feet? Round to the correct significant digits.
OleMash [197]
The area of a square is s•s.
A= 6.25•6.25
A= 39.0625
Rounded= 39.06 square feet
(I'm assuming rounding to the significant digits means rounding to the hundredths since 6.25 is rounded to the hundredths.)
