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?
81 will be 9
100 will be 10
So I think it’s c which is 9/10
Which is also 0.09
A = s^2
To find side of length
81/100 = s^2
sqrt(81/100) = sqrt(s^2)
9/10 = s
To find the side length of a square postage stamp, we can use the formula for the area of a square. The formula for the area of a square is:
Area = side length * side length
Given that the area of the stamp is 81/100 in², we can plug this value into the formula to solve for the side length.
81/100 = side length * side length
To solve for the side length, we can take the square root of both sides of the equation:
√(81/100) = √(side length * side length)
√(81/100) = side length
Now, we can simplify the square root of 81/100:
√(81/100) = √(9/10)²
√(81/100) = 9/10
Therefore, the side length of the square postage stamp is 9/10 inches.
So, the answer to your first question is that the side length of the stamp is 9/10 inches.
As for your second question, the formula of the area of a square is Area = side length * side length.
