Answer:
813 N/m²
Step-by-step explanation:
The units of pressure tell you it is found by dividing force by area. Here, we need to convert the units of the given area so we can express the pressure appropriately.
__
pressure = force / area
pressure = (61 N)/(750 cm² × ((1 m)/(100 cm))²) = (61 N)/(0.0750 m²)
pressure ≈ 813 N/m²
