A square postage stamp has area 1 comma 150 mm^2. About how long is each side?
To find the length of each side of the square postage stamp, we will need to find the square root of the area.
Since the area of the square postage stamp is 1,150 mm^2, we will find the square root of 1,150:
√1,150 ≈ 33.83
Therefore, each side of the square postage stamp is approximately 33.83 mm in length.
