If a room has a square footage of 1400 feet and one side is 25ft long, what is the length of the other side?

In a room that has a square footage of 1400 square feet, if one side measures 25 feet long, the length of the other side can be determined by using the formula for the area of a rectangle (or square) which is length multiplied by width. Here, one side is given as 25 feet.

To find the other side, you can divide the total area by the length of the known side:

Area = Length × Width

Width = Area / Length

Substituting the known values:

Width = 1400 square feet / 25 feet

Calculating this gives:

Width = 56 feet

Thus, the length of the other side is 56 feet. This aligns with the option selected, confirming that it is indeed the correct answer.
