given , 
area in contact = 80 cm
² = 0.008 m²
80 kilogram - force = 784.532 N
therefore pressure = force / area 
= 784.532 / 0.008 
= 98066.5 Pa 
therefore the answer is 98066.5 Pa 
              i hope it helps..........................^_^

sorry but what u said is not the exact answer
den wht is d ans 
area= 80cm2 = 2×80÷10-⁴ force = 784N pressure = F÷A = 784 × 10⁴÷2×80 = 4900 = 4.9 × 10³
