Answer :
The pressure exerted on the elevator floor by 20 people with a combined weight of 1500 N is 250 N/m^2 or Pascals (Pa).
To calculate the pressure exerted on the elevator floor by the 20 people with a combined weight of 1500 N, we use the formula for pressure, which is Pressure (P) = Force (F) / Area (A). In this case, the force is given by the weight of the people, and the area can be calculated from the dimensions of the elevator floor. The floor has a length of 2 meters and a width of 3 meters, so its area
A is 2 m x 3 m = 6 m2.
\Therefore, the pressure P is
1500 N / 6 m2 = 250 N/m2 or Pascals (Pa).
