If the lengths of an object are measured in feet, then the area of the object will be measured in which of the following units of measurement?

ft * ft = ft^2

To determine the unit of measurement for the area of an object, we need to consider the units used for length. In this case, since the lengths of the object are measured in feet, the unit of measurement for the area will be square feet (ft²).

The reason for this is that when measuring the area of a 2-dimensional object, such as a rectangle or a square, we need to multiply two lengths together. In this case, multiplying feet by feet (ft × ft) would result in square feet. This is because we are multiplying the length of one side by the length of the other side, resulting in the unit of measurement being squared.

So, if the lengths of an object are measured in feet, the area of the object will be measured in square feet (ft²).
