The width of the garden is 99 feet.

Step-by-step explanation:

Given: The perimeter is 306 ft.

Given: the length of the garden is 99 ft.

Step 1: Because the garden is rectangular and so 2 of its sides are the lengths, we must multiply 99 by 2. 99x2=108.

Step 2: To find out the 2 remaining sides of the garden (the widths), we must subtract the perimeter by the lengths. 306-108=198.

Step 3: Because there are 2 sides which are the widths, we know that they are each equal and add up to 198. To find out how long the width is, we must divide the 2 widths by 2. 198/2=99.

So, the width of the garden is 99 feet.
