Answer :
Final answer:
The total area of the elephant's feet is 0.4 square metres. The pressure it exerts is 150000 Pa (Pascals).
Explanation:
To find the total area of the elephant's feet, you should multiply the area of one foot by the number of feet. Since the area of one foot is 0.1 square metre and the elephant has four feet, the total area is 4 * 0.1 = 0.4 square metres.
Pressure is defined as the ratio of force to the area over which it is distributed. So to calculate the pressure the elephant exerts, we have to divide its weight by the total area of its feet. Since the weight of the elephant is 60000N, the total pressure is 60000N / 0.4sq.m = 150000 Pa (Pascals).
