A gardener is planning to fill her garden with mulch. She plots it on a grid to plan how much she will need. The garden is in th
e shape of a rectangle with vertices at (2, 5) (8, 5) (8, 3) and (2, 3). One bag of mulch covers 6ft2 and costs $5.25. How much will it cost her to cover her garden?
First is to know length and width of the rectangular garden. length of the garden is difference in the x coordinates L = 8 - 2 = 6 ft while the width is the difference in the y coordinates
w = 5 - 3 = 2 ft
now we can solve the area of the rectangular garden. A = Lw A = 6 x 2 = 12 sq ft
