Question

find the perimeter of a rectangular feild whose breadth is 42.5 cm ans its length is double of the breadth​

Answer 1

PERIMETER OF RECTANGLE= 2(l+b)
=2(42.5*2+42.5)
=2(85+42.5)
=2*3612.5
=7225.
Hence, the perimeter of rectangular field is 7225cm.

Answer 2

Answer:

first we have to find length

length is 2 times of bredth=42.5*2=85

length is 85cm

perimeter of rectangle=2(length+bredth)

=2(85+42.5)cm

=2*127.5 cm

=255 cm

perimeter is 255 cm
