The are of a rectangular community the graden is 300 square feet. The length of a rectangular graden is three times its width. Find the length and width of the graden.

length: 30 ft width: 10 ft

Step-by-step explanation:

The description of the garden fits that of 3 squares arranged side-by-side. The area of each of those would be 100 ft², so their side length would be ...

s = √A = √ (100 ft²) = 10 ft

This dimension is the width of the garden, whose length is 3 times this amount.

The length and width of the garden are 30 ft and 10 ft, respectively.
