(i) What is the area of the field ?
(ii) Is the area of the field a perfect square number ? Justify your answer.
(iii) What is the length of side of the field ?

Answer 1

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
