The perimeter of a rectangle is the sum of its sides, which are two widths and two lengths:

Since the length is twice the width, we have
, and the formula for the perimeter becomes

So, we have

Tada, Its on the Image. Hoped I helped :)
Recall that tanA = sinA / cosA.
Therefore, tanA = (3/5) / (4/5) = 3/4.
