The playground has a total size of 1600 m2. What is the size of the perimeter? I. It's a square playground to the nth degree. II. At a rate of Rs. 20 per metre, erecting a fence around the playground costs Rs. 3200.
A. I alone sufficient while II alone not sufficient to answer B. II alone sufficient while I alone not sufficient to answer C. Either I or II alone sufficient to answer D. Both I and II are not sufficient to answer
Explanation: 1600 m2 in size.I. Side = 1600 m = 40 m; II. Side = 1600 m = 40 m; III. Side = 1600 m As a result, the perimeter is (40 x 4) m = 160 m.I am the only one who can provide an answer.Perimeter = Total cost = 3200/20 m = 160 m Cost per metre II by itself provides the solution.
