A rectangular garden has a perimeter of 16 m. The length is 2 m more than the width. What is the width of the garden?
📘 Worked solution
12((w + 2) + w) = 16Let w be the width. The length is w + 2, and perimeter is 2(length + width).
24w + 4 = 16Distribute the 2 and combine the w-terms.
34w = 12Subtract 4 from both sides.
4w = 3Divide both sides by 4.
5Check: length = 3 + 2 = 5, perimeter = 2(5 + 3) = 16.Substitute the width back in -- the perimeter matches, so the solution checks out.
