Answer:
%
Step-by-step explanation:
Surface area of a human body is given by -

Taking integral on both sides, we get -

Since, the at most error in the surface area of a human body is
%
Substituting this in above equation, we get -
![\frac{dS}{S} \leq [0.425*0.02 + 0.725*0.02]\\\frac{dS}{S} \leq0.023\\](https://tex.z-dn.net/?f=%5Cfrac%7BdS%7D%7BS%7D%20%5Cleq%20%5B0.425%2A0.02%20%2B%200.725%2A0.02%5D%5C%5C%5Cfrac%7BdS%7D%7BS%7D%20%5Cleq0.023%5C%5C)
Thus, the maximum error is surface area is equal to
%
The only solution is (-3/2, 4)
