Question

hari ram has to put a fence around his rectangular field of length 15m and breadth 10 m what is the length of the fence needed?if he has fenced 20 m how much more fence is needed to complete the boundary?

Answer 1

Length = 15m

& breadth= 10m

. '. Perimeter of the rectangle =

2(length + breadth)

=2(15+10)

=2*25

=50m

Length of the fence needed =(50-20) m

= 30m

More 30m fence is needed

Answer 2

Answer:

Additional Fence Needed = 30m

Step-by-step explanation:

To put a fence around his rectangular field of length 15m and breadth 10m, Hari Ram needs to calculate the perimeter of the field, which is the total distance around the field. The formula to find the perimeter of a rectangle is:

Perimeter = 2 x (Length + Breadth)

So, the perimeter of Hari Ram's field is:

Perimeter = 2 x (15m + 10m)

Perimeter = 2 x 25m

Perimeter = 50m

Therefore, Hari Ram needs 50 meters of fence to enclose his rectangular field.

If Hari Ram has already fenced 20 meters, he needs to calculate how much more fence he needs to complete the boundary. To do this, he can subtract the length of the fence he has already put up from the perimeter of the field:

Additional Fence Needed = Perimeter - Length of Fenced Portion

So, the additional fence needed by Hari Ram is:

Additional Fence Needed = 50m - 20m

Additional Fence Needed = 30m
