the slipperiness of a floor (demoted by S) can be defined as a function of the number or banana peels (denoted by P) and the are

QveST [7]

We have been given that the slipperiness of a floor (demoted by S) can be defined as $S=\frac{P}{A}$

Here P= number or banana peels

A=area of the floor

Number of bananas peels can be measured (units ) in peels

Area can be measured in $m^2$

Since, slipperiness of a floor is the ratio of these two hence, we have

$\text{slipperiness of a floor}=\frac{\text{Peels}}{m^2}$

A is the correct option.
