Answer:
Given:-
Perimeter of rectangle =36 feet
Length of rectangle is 2 less than 3 times its width.
Let 'w' be the width of rectangle. Length=3w-2(as length is 2 less than 3 tines width)
According to the formula of perimeter of a rectangle, 2(l+b),
2(3w- 2+w)=36
6w-4+2w=36
Keeping the like terms together,
6w+2w-4=36
8w-4=36
8w=36+4
8w=40
w=40/8
w=5 feet
l=3w-2
So, substituting the values, we have:-
3×5–2
15–2
13feet
Therefore,w=5 feet
And
l=13 feet
