A rectangle is 3 times as long as it is wide the perimeter is 44 cm. find the dimensions

Well!

First let the length be 'l' and breadth be 'b'

So, perimeter = 2 (l + b)

Given that,

Length is thrice the breadth

l = 3b

Now, substitute it in the formula for perimeter!

44 = 2 (3b + b)

44 = 8b

b = 44/8 = 11/4 cm

l = 3b = 11/4 * 3 = 33/4 cm
