what is the size of the width?

Question

The side length of a rectangle is 3 less than double the width. if the side length of the rectangle is 127 cm, what is the size of the width?

Answer 1

Given L = 127

Let L = 2W - 3 set up equation

127 = 2W - 3 add 3 to both sides

130 = 2W divide both sides by 2

65 = W

Therefore the width of the rectangle is 65 cm.
