Answer» Answer: Step-by-step EXPLANATION: This is your answer..... Given ::: DIAMETER = 42 m. Radius = D/2 = 21 m. We have to find the length of circular garden. So.... We will obtain perimeter.... P of Circle = 2 × 22/7 × 21 = 6 × 22 = 132 m. Hence the length of BOUNDARY is 132 m. But the gardener takes three round OD the fence... So length of wire needed = 3× 132 = 396 m. Hence the length of wire needed is 396 m |
