Length of the rectangular plot (perimeter)=150cm
let breadth=x
length be 2x
therefore perimeter = 2(l+b)
or, 150 = 2(2x+x)
or, 150 = 4x +2x
or, 150 = 6x
or x = 150รท6=25
breadth is equals to x is equal to 25 CM
and length is equal to 2 x is equal to 50 cm

2L + 2B = 150m
Given, L = 2B
therefore, 2(2B) + 2B = 6B = 150m
B = 150m/6 = 25m
L = 2(25m) = 50m
