a rice field is pentagon in shape. The length of its sides are 105 m 215 m 158 m 197 m and 155 m respectively. If the owner wants to fence it with three strands of barbed wire How many meters of wire in all will be needed?
To find the perimeter of the rice field, we need to add the lengths of all five sides:
105 m + 215 m + 158 m + 197 m + 155 m = 830 m
Since the owner wants to fence it with three strands of barbed wire, we need to multiply the perimeter by 3:
830 m * 3 = 2490 m
Therefore, a total of 2490 meters of wire will be needed.
