Answer:

Area 1 is the best option

Step-by-step explanation:

Given Data:

Area 1 = 0.75 dam square

Price = €11,620

Area 2 = 0.009 ha

at €193,500

Area 3 = 0.84a

at €68,900

Where ha ( hectare )

a ( area )

Solution

First we convert all areas to square meter ( m² )

Area 1 = 100 * 0.75 dam square

= 75m²

Cost of area 1/ square meter

= €11,620 / 75m²

= €154.93 / square meter

Area 2 = 0.009 ha * 10,000

= 90m²

Cost of area 2 / square meter

= €193,500 / 90m²

= €2,150 / square meter

Area 3 = 0.84a * 100

= 84m²

= Cost of area 3 / square meter

= €68,900 / 84m²

= €820.23 / square meter
