Question 393709: If the numerical value of the area of a retangle is twice the length and the length is 1 more than 3 times the width, what are the dimensions?
area = L * W
w = x
L = 2x + x
2x + x = x(3x + 1

Hi

Let x and (3x + 1)represent the width and length respectively

Might recommend using the above format prior to Writing the Equation

Question states*** A = L*W

 L*W     = 2*L   the question states is true in this  question

 x(3x+1) = 2(3x + 1)

      x = 2, the width. the length is 7  (3*2 + 1)
