The area of a 2D form is the amount of space within its perimeter. The cost of covering the garden is $12.
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
When all the coordinates are plotted it can be seen that the length of the rectangle is 2ft (5 - 3), while the width is 6ft (9 - 3). Therefore, the area of the field will be,
Area of the garden = 2ft × 6ft = 12ft²
Given the cost of one bag of mulch which covers 5 ft² is $5, therefore, the cost of covering a square ft of the garden will be,
Cost of covering a square feet = $5/5ft² = $1 per sq. ft.
Now, since the area is 12 ft², the cost wil be,
Cost of covering the garden = 12 ft² × $1 = $12
Hence, the cost of covering the garden is $12.
