Question

If a square floor has an area of 260 square feet, estimate the length of one side. Give the whole number that is closest to the amount.
A. 18 feet
B. 17 feet
C. 16 feet

Answer 1

Answer is 16.
To estimate, you assume the floor is a perfect square, which would make the area equal to one side length squared.
Hence the side length is given by sqrt(260), which is approximately 16.

Answer 2

side =\[\sqrt{260} = \pm16\] take the positive one, ie 16

Answer 3

thank you
