A rectangular plot of land measures 40m by 30m. There is a wall on one of the longer sides. Four strands of wire are to be used to fence the three remaining sides of the plot. What length of wire is required?

To find the length of wire required to fence the three remaining sides of the plot, we need to calculate the perimeter of the plot.
Perimeter of a rectangle = 2 × (length + width)
Given that the length of the plot is 40m and the width is 30m, we can substitute these values into the formula:
Perimeter = 2 × (40 + 30)
Perimeter = 2 × (70)
Perimeter = 140m
So, the total length of wire required to fence the three remaining sides of the plot is 140 meters.
