A farmer wishes to fence his field with 3 rows of wire.if the dimensions of the field are 120m by 68m,find the total length of wire required
1128cm
3*2*(120+68) = 1128m
To find the total length of wire required, we need to calculate the perimeter of the field, taking into account the three rows of wire fencing.
The dimensions of the field are given as 120m by 68m. To calculate the perimeter of a rectangle, we use the formula:
Perimeter = 2(Length + Width)
In this case, the length is 120m and the width is 68m, so the formula becomes:
Perimeter = 2(120 + 68)
Perimeter = 2(188)
Perimeter = 376m
Since the fence consists of three rows of wire, we need to multiply the perimeter by 3 to get the total length of wire required:
Total length of wire = Perimeter x 3
Total length of wire = 376m x 3
Total length of wire = 1128m
Therefore, the farmer needs a total length of 1128 meters of wire to fence his field with three rows.
