To calculate the pressure created by a given body on the support area, we will use the formula: P = Fт / S = m * g / S.
Constants and variables: m (mass of a given body) = 30 kg; g (acceleration due to gravity) ≈ 10 m / s2; S (reference area) = 20 cm2 = 20 * 10 ^ -4 m2.
Calculation: P = m * g / S = 30 * 10 / (20 * 10 ^ -4) = 150 * 10 ^ 3 Pa (150 kPa).
Answer: The pressure on the support area is 150 kPa.
