Answer:
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
