Arectangular field measures 81
meters by 117
meters. what will it cost to cover the field with pallets of grass each covering 90 square yards and costing $210
per pallet? (hint: 1 yd almost equals 0.9 m
)

It will cost $27300 to cover the field with grass

Step-by-step explanation:

* Lets explain how to solve the problem

- The field shaped rectangle with dimensions 81 and 117 meters

- The field with covered by grass

- The pallets of the grass covering 90 yard²

- The cost of the pallet is $210

* At first lets change the dimensions of the field from meter to yard

∵ 1 yard = 0.9 meter ⇒ multiply both sides by 10

∴ 10 yards = 9 meters ⇒ divide both sides by 9

∴ 1 meter = 10/9 yards

∵ The dimensions of the field are 81 and 117 meters

∴ 81 × 10/9 = 90 yards

∴ 117 × 10/9 = 130 yards

- Remember that the area of the rectangle = length × width

∵ The dimensions of the field are 90 and 130 yards

∴ The area of the field = 90 × 130 = 11700 yards²

- Lets find the number of pallets which uses to cover the field by

 divide the area of the field by the area covering by one pallet

∵ The pallet covering 90 yards²

∴ The number of pallets = 11700 ÷ 90 = 130 pallets

- You need 130 pallets to cover the field

∵ The cost of one pallet is $210

∴ The cost to cover the field = 130 × 210 = $27300

* It will cost $27300 to cover the field with grass

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
