Explanation:
Given:
Perimeter of the garden=84 feet
Let the width of the garden be 'W'
Length of the garden is 24 feet longer than the width of it
so, length of the garden= W+24 feet
To find the width 'W'
Perimeter of a rectangle= 2(Length+Width)
feet
Width=9 feet
Length=W+24= 9+24= 34 feet
Area of the garden= Length*width
![=34*9\\ =306 feet^2](https://img.qammunity.org/2021/formulas/mathematics/middle-school/zvp0dn4i0sg7flfbx7bfybte8g4tokrb0d.png)
Area of the garden is 306 square feet
