Raymond cut out a square from a piece of construction paper. The area of the square was greater than 25 square centimeters and less than 100 square centimeters. Which of the following best describes x, the length in centimeters of a side of his square?
we know that
The area of a square is equal to
A=x^2
where x is the length side of the square
we have that
A > 25 cm^2
A <100 cm^2
If the area A=25 cm^2
then
25=x^2
x=5 cm
If the area A=100 cm^2
then
x=10 cm
therefore
the value of x lie in the interval (5,10)
option b is the answer
