Let L be the length
Let W be the width
now,
L = 3W
Area of rectangle is L x W = 147
Substituting L = 3W in above equation.
3W x W = 147
3WSquare = 147
Wsquare = 147/3
Wsquare = 49
so w =7

L=3W
LW=147
3WW=147
WW=49
W=7

A= L* W
L= 3W
147 = 3W(W)
441=W SQUARED
W=41

W= x
L= 3x
A=L*W
A=3x*x
A=3x^2
147=3x^2
divide by 3
49= x^2
find the square root
7=x
W=7
L=21

Think of it this way:
L= 3w
W=
A= 147 sq ft
A= L*w
Soo.. lemme see if I can remember...
(3w)*w=A
A=147 sq ft.
I'll leave the rest for you to figure out.
