Question

The width of a rectangular field is 20 metres. The
field is twice as long as it is wide. Determine its
perimetre​

Answer 1

given

breadth of rectangular field =20

length is twice its width =20×2=40

parameter =2(length +breadth)

=2(40+20)

=2×60

=120

thus the parameter of rectangular field =120

Answer 2

Answer:

Step-by-step explanation:

Width =20m

Then length=20×2=40m

Perimeter of rectangle=2(l+b)m

=2(20+40)m

=120m
