Question

A rectangular piece of land measures 7km by 5km . Each side is to be fenced with 4 rows of wires. What is the length of the wire needed?

Answer 1

length of wire needed is the perimeter of the field i.e. 24 km

hope this helps

Answer 2

Answer:96km

Step-by-step length of the field =7km

Breadth of the field=5km

Perimeter of rectangle=2*(length +breadth)i.e. 2*(7+5)=24

Now we have to make 4 rounds on each side therefore we multiply 24 by 4 which equals to 96.
