A variable cost is a constant amount per unit produced or used. Therefore, the total amount of the variable cost will change proportionately with volume or activity. Generally, a product's direct materials are a variable cost. To illustrate, let's assume that a bakery uses one pound of flour at a cost of $0.70 per pound for every loaf of bread it produces.
Most sports fields are one hectare in size. The Apple Bowl in Kelowna for instance is a 400 m running track and the grassy area inside is 1.12 hectares. The international rugby field pictured above is very close to one hectare in size, it is actually 1.0008 hectares. A perfect square is 100 meters by 100 meters is a hectare.

All surveyed land should be in Metres X Metres ( Sq M ). A plot can be 850 Sq M or 1,200 Sq M so anyone involved in land transaction should ask the land vendor what the size of the plot for sale is in Square Metres, it's as simple as that. By the way One Hectare is 10,000 Sq M and an Acre is 4,046.85 Sq M . One Acre is roughly 40% of a hectare.
