Question

2. A rectangular field is 725 m long and 300 m broad. Find its perimeter in km and m.
3. A side of a square field is 300 m. Find its perimeter in km.
4. A square field has a side 525 m. I run 2 times round it. How much distance do I travel?
5. A field has length 350 m and breadth 300 m. Find the length of wire needed to fence around it
6. A square courtyard is 8 metres in length. Find the length of wire required to fence around it​

Answer 1

Answer:

Step-by-step explanation:

2 . Total perimeter in meters = 2(l+b) = 2(725+300) meters

     = 2050 meters = 2.05 kms

3 . Perimeter of a square = 4*side

     = 4*300 meters = 1200 meters = 1.2kms

4 . Distance travelled by you = 2*4*side of the square

     = 2*4*525 meters = 4200 meters = 4.2 kms

5 . Length of wire = 2(l+b)

     = 2(300 + 350) meters = 1300 meters = 1.3 kms

6 . length of wire = 4*side of the square

     = 4*8 meters = 32 meters
