Final answer:
The length of a rectangular field with an area of 8342 m² and a width of 86 m is found using the formula for the area of a rectangle, resulting in a length of 97 meters.
Step-by-step explanation:
The question asks for the length of a rectangular field, given that the area of the field is 8342 m² and the width is 86 m. To find the length, we can use the formula for the area of a rectangle, which is Area = Length × Width. We rearrange this formula to solve for the length, giving us Length = Area ÷ Width.
Length = 8342 m² ÷ 86 m = 97 m
Therefore, the length of the field is 97 meters.
