Answer:
A farmer wants to fence his rectangular field with three strands of wire. If his field is 150 m long and 80 m wide, then the length of wire required by the farmer is 460m.
Step-by-step explanation:
Given: Length of rectangular field = 150 m
Width of rectangular field = 80 m
Find: The length of wire required by the farmer.
Formula: Perimeter of rectangle = 2 (length + breadth)
If we want to find the length of wire required by the farmer means to find the perimeter of the rectangle.
Perimeter of rectangle = 2 (length + breadth)
= 2 (150 +80)
= 2 (230)
= 460 m
Hence the length of wire required by the farmer is 460 m.
Answer:
The length of the wire needed is 1380 meters.
Step-by-step explanation:
The length of the rectangular field is 150 meters.
The width of the rectangular field is 80 meters.
In case of a rectangle , if the length of a rectangle is L and the width of that rectangle is W then the perimeter of the rectangle is ,
2 × ( length + width ) = 2 × ( L + M )
In this case , L = 150 m and M = 80 m
Then the perimeter of the rectangular field is ,
2 × ( L + M ) = 2 × ( 150 + 80 ) = 2 × 230 = 460 meters.
∴ The length of the wire needed is ( 460 × 3 ) = 1380 meters
