Answer:
(i) 2304m² , (ii) Yes & (iii) 48m
Step-by-step explanation:
(i) The area of the field = (Total cost of ploughing)/(Cost of ploughing per m²)
= 34560/15 = 2304 m²
(ii) Yes, 2304 is a perfect square number because root under 2304 = 48 ie. a whole number.
(iii) The length of the side of the field = root under area = root under 2304 = 48 m
