Question

the perimeter of a rectangular garden is 150 feet the length is 50 feet longer than the width w which equation could be used to calculate the width of the garden

Answer 1

Let the width be w and the length be w + 50. The perimeter is 2(length + width) = 150, so

2[w + (w + 50)] = 150

You can simplify and solve: 4w + 100 = 150 → 4w = 50 → w = 12.5 feet.
