Let the width be x. Then length is 3x.
Notice that when we take two sides with its diagonal we have a right triangle.
Apply pythagorean theorem.
<---width
Then our length is 18.
P = 2L + 2W
P = 2(6) + 2(18) = cm

Let width be x then the length will be 3x
by Pythagoras theorem,
x=6
length = 18, Breath = 6
Perimeter = 2(18+6)
= 48 cm
