Final answer:
The ant wearing platform heels with a total area of 7 cm² would exert a pressure of approximately 285,714.29 Pascal (Pa).
Step-by-step explanation:
To calculate the pressure an ant would exert with platform heels, we use the formula P = F/A, where P is pressure, F is force (in this case, the ant's weight), and A is the area over which the force is distributed. Given that the ant weighs 200 N and the platform heels have a total area of 7 square centimeters, we can convert the area to square meters by dividing by 10,000 (since there are 10,000 cm² in 1 m²). So, the area in square meters is 0.0007 m². The pressure exerted can be calculated as 200 N / 0.0007 m² = 285714.29 Pa (to two decimal places). Thus, the ant would exert a pressure of about 285,714.29 Pascal (Pa) on the surface.
