Question

Four poles are stuck into the square garden of side 30 m at the four corners. A rope fence is to be put around the poles. What length of rope will be required if 2m is required for tying the each knot?​

Answer 1

Answer:

Total rope= 120+8=128m

Step-by-step explanation:

Perimeter of rope required= 4×30= 120m

Extra rope for tying= 4×2=8m

Answer 2

Answer:

Since poles are at each vertex of the given square....

So rope required for fencing will equal to perimeter ignoring knot lengths

Perimeter = 4S

P = 4*30

P = 120m

And extra rope will also be needed to tight ropes

In question Extra = 4*2m = 8m

So ... Required length of rope

Required = P + E

Length = 128m
