Answer:
a) 4w + 16 = 50.
Step-by-step explanation:
The garden's length is obviously 8 feet longer than the width. If width were represented by w, the length would be w + 8.
We are calculating the perimeter, which is 2 times the length plus 2 times the width. That adds up to be 50.
2(w) + 2(w + 8) = 50
2w + 2w + 16 = 50
4w + 16 = 50
So, the answer is a) 4w + 16 = 50.
Hope this helps!
