Question

If a regular decagonal field is fenced with a 2250 cm wire mesh, show by calculations the length of each side in metres

Answer 1

Answer:

2.25 m

Step-by-step explanation:

The length of the wire mesh used to fence the field will be its perimeter since it covers all the edges of the field and forms its boundary.

Perimeter of field = Length of Wire Mesh = 2250 cm = 22.50 m

Now, it is a regular decagonal field,i.e., all its sides are equal.

Hence,

Length of each side ( in metres ) = Perimeter/Total no. of Sides = 22.50/10 = 2.25 m

Answer 2

Answer:

Answer:Here it is given that the decagonal field is fenced with a wire mesh of 2250 cm all around it which means that we are given the perimeter of the decagonal field as 2250 cm. Thus, the length of each side in meters is 2.25 m.

Step-by-step explanation:

Let "a" cm represent each side of the decagonal field.Here it is given that the decagonal field is fenced with a wire mesh of 2250 cm all around it which means that we are given the perimeter of the decagonal field as 2250 cm.perimeter = 10 a there fore we get 10 a= 2250a= 2250/10a= 225 cam now, we have convert the length of the side in metersif 1 cm = 1/100m then 225 cam = 225/100m = 2.25 m so, the length of each side in meters is 2.25 m
