Let l be the length and w the width of the rectangular garden
Since its area is 300 ft², we have:
l*w = 300 ft²
Since the length is three times its width, we have:
l = 3w
Replacing l with 3w in the first equation, we have:
3w² = 300
w² = 100
w = 10 ft
Then, the length is given by:
l = 3*10
l = 30 ft
Answer:
length = 30 ft
width = 10 ft
