There are 6 rectangular flower gardens each measuring 18 feet by 13 feet in a rectangular city park

measuring 70 feet by 160 feet.

How many square feet of the park are not used for flower gardens?

How many ft are not used for flower gardens.

Step-by-step explanation:

The formula for determining the area of a rectangle is expressed as

Area = length * width

There are 6 rectangular flower gardens each measuring 18 feet by 13 feet in a rectangular city park. The area of each garden is

Area = 18 * 13 = 234 ft²

Since there are 6 gardens, the total area covered by the 6 gardens is

6 * 234 = 1404 ft²

The rectangular park measures 70 feet by 160 feet. The total area of the park is

Area = 70 * 160 = 11200 ft²

The number of square feet of the park that is not used for flower gardens is

11200 - 1040 = 10160 ft²

The formula for determining the perimeter of a rectangle is

2 (length * width)

Total number of feet covered by rectangular city park is

2 (70 + 160) = 460 ft

Number of feet covered by the 6 rectangular gardens is

6[2 (18 + 13) ] = 372 ft

The number of feets not used for flower gardens is

460 - 372 = 88 feet
