Perimeter of  a rectange is given by
P = 2(l+b)
400= 2 (20 + b)
20+b = 200
b = 180
So the breadth is 180m

So let the length be l = 20 m

and the breadth be b

so perimeter = sum of the length of the four sides = 2l + 2b

so perimeter = 400 = 2(l + b)

⇒l + b = 200 

⇒ b = 200 - 20 = 180 m ANSWER

what?
no a doesnt..
ohh achha
no small a doesn't have any line of symmetry but " A " has 1 line of symmetry
yup right
