Answer:

Length of the rectangle = 43 inches

Width of the rectangle= 20 inches

Step-by-step explanation:

  • Let the width (w) of the rectangle be = x inches

  • -> Length (l) of the rectangle will be = (2x + 3) inches.

  • Perimeter of the rectangle = 126 inches

  • -> 2(l + w) = 126

  • -> l + w = 126/2

  • -> l + w = 63

  • -> x + (2x + 3) = 63

  • -> 3x = 63 - 3

  • -> 3x = 60

  • -> x = 60/3

  • -> x = 20

  • -> 2x + 3 = 2(20) + 3 = 43

  • Thus,

  • Length of the rectangle = 43 inches

  • Width of the rectangle= 20 inches
