Given :
- A rectangular piece of land measures 0.7 km by 0.5 km.
- Each side is to be fenced with 4 rows of wires.
To Find :
- What is the length of the wire needed?
Solution :
As we know that
→ Perimeter of rectangle = 2(length + breadth)
→ Perimeter of rectangle = 2(0.7 + 0.5)
→ Perimeter of rectangle = 2 * 0.7 + 2 * 0.5
→ Perimeter of rectangle = 1.4 + 1
→ Perimeter of rectangle = 2.4
Now,
The length of the wire needed = 4 rows * Perimeter of rectangle piece.
→ Wire needed = 4 * 2.4
→ Wire needed = 9.6
Hence, the length of the wire needed are 9.6 km.
Given:- dimensions of rectangular piece of land are 0.7km and 0.5km. And each side is to be fenced with 4 rows of wires.
To find:- the Length of wire needed for fencing.
Solution :-
Let the length of rectangle field is 0.7 km and breadth of rectangle field is 0.5 km.
⇒ Perimeter of rectangle field,
= 2 (length + breath)
= 2 (0.7+0.5)
= 2.4km
Now, length of fencing field will be equal to 4 times the perimeter of field.
⇒Length of fencing field,
= 4 × perimeter
= 4 × 2.4km
= 9.6km
Therefore, the length of wire needed is 9.6 km.
