Find the lamp of the side of a square with an area of 121 in 2

Answer 1

If the area of the square is 121 in^2, then the length of each side is the square root of 121, which is 11 inches.

To find the lamp of the side of the square, we need to multiply the perimeter of the square by the number of lamps per unit length.

If we assume that there is one lamp per foot, then we need to convert the length of each side from inches to feet by dividing it by 12:

11 inches / 12 = 0.9167 feet

The perimeter of the square is equal to four times the length of one side:

Perimeter = 4 x 11 inches = 44 inches

We then convert this to feet by dividing by 12:

44 inches / 12 = 3.67 feet

Finally, we multiply the perimeter by the number of lamps per unit length:

3.67 feet x 1 lamp/foot = 3.67 lamps

Therefore, the lamp of the side of the square with an area of 121 in^2 is approximately 3.67 lamps. However, it is not possible to have a fractional number of lamps, so we would need to either round up or down depending on the specific situation.
