text: 1) a small field is of rectangle form 34.5m*23.3m? (a)(i) find the area of the field in m^2    (ii)find the area in ha.  (b)(i) if the dimensions are rounded to the nearest whole meter, what would be the area in m^2.       (ii)express your answer to (i) in the form a*10^k where1 is less than a<10 and k e z     (iii) if you use the result from (i) as the area, what would the percentage error be? (a)(i)803.85 m^2 (don't know to multiply?) (ii) .080385 ha (10000 m^2 = 1 ha)  (b)(i)34*23 = 782 m^2  (ii) 7.82 * 10^2 m^2 (iii) 21.85/803.85 * 100 = 2.72 %  p.s.: this was a simple one. why do you ask?
