Question

the length of a rectangular field is twice is breath and the area is 2 hectares find the cost of fencing the field at rupees 50 per metre​

Answer 1

Step-by-step explanation:

the breadth (b) of the rectangular field be x

∴length(l)=2x

As we know that, perimeter of rectangle (P) is given as-

P=2(l+b)

⇒P=2(2x+x)

⇒P=2(3x)

⇒P=6x

Given that perimeter (P) of the rectangular field is 60m

∴6x=60

⇒x=

6

60

=10m

Therefore,

Breadt of the field =10m

Length of the field =2×10=20m
