Question
The area of a square postage stamp is 81/100 in. squared. What is the side length of the stamp? What is the formula of the area of a square?
Answers
A = s^2
To find side of length
81/100 = s^2
sqrt(81/100) = sqrt(s^2)
9/10 = s
To find side of length
81/100 = s^2
sqrt(81/100) = sqrt(s^2)
9/10 = s
I got 0.81
81 will be 9
100 will be 10
So I think it’s c which is 9/10
100 will be 10
So I think it’s c which is 9/10
Which is also 0.09
