The length of the rectangle is 1.1 meters less than the width. The perimeter of a rectangle is 49.4 meters. Find the dimensions of the rectangle.

11.8 x 12.9

Step-by-step explanation:

Perimeter = 2 length + 2 width. Let L = length and W = width.

Length is 1.1 less than width, so L = W - 1.1

49.4 = 2(W - 1.1) + 2W

49.4 = 2W - 2.2 + 2W

51.6 = 4W                                add 2.2 to both sides and combine like terms

12.9 = W

L = 12.9 - 1.1 = 11.8
