What is the approximate value of √5 on a number line?

Back

Point K: √5 is approximately 2.236, which is between 2 and 3 on the number line.

Front

If the area of a rectangle is 500 in², what is the length of one side if the other side is 25 in?

Back

22 in: Area = length × width, so 500 = length × 25, thus length = 500 / 25 = 20 in.
