Let the length of rectangle is l and width is w …
Then according to the question ..
l = 2w..
Given..
Perimeter = 36 unit
We know that –
Perimeter = 2( lenth + width)
And l = 2w then..
36 = 2( 2w + w)
3w = 18
W = 6 and
l = 2*6
l= 12
Then lenth of rectangle of will be 12 and width of rectangle will be 6.
