Answer:
138 meters
Step-by-step explanation:
To find the length of the chain link wire used to fence a rectangular plot, we need to calculate the perimeter of the rectangle. The perimeter is the total distance around the edge of the rectangle.
Add the lengths of all four sides of the rectangle.
Since the opposite sides of a rectangle are equal, we have two sides that are 42 meters and two sides that are 27 meters.
So, you add 42 meters + 42 meters for the longer sides and 27 meters + 27 meters for the shorter sides.
The formula for the perimeter (P) is: P=2×length+2×width
Using the measurements provided:
P=2×42m+2×27m
P=84m+54m
P=138m <---- Answer
