Question

Although the preferred SI unit of area is the m^2, land is often measured in the metric system in hectares. One hectare is equal to 10,000 m^2. In the English system, land is of ten measured in acres (1 acre = 160 red^2. Use the react conversion and those given. 5 1/2 rods = 1 rod 1/0 rods = 1 furlong 8 furlongs = 1 mile. The area of 4.5 acre plot of land in hectare, m^2, and km^2 A lot with dimensions 130 ft by 75 ft is to be sold for $7100. What is the price per acre? $ What is the price per hectare?

Explanation / Answer

Solved first two problems, post multiple question to get the remaining answers

[1]

1 ha = 10000 m^2

1 Km = 1000 m

1 ha = 10000 m^2 * (1 km/1000m)^2 = 10^4/10^6 * Km^2 = 0.01 Km^2

[2]

1 acre = 160 rods^2= (160/40*40)^2 furlong^2 = 0.1 furlong^2 = (0.1/8*8) mile^2 = 0.0015625 mile^2

4.5 acre = 0.00703125 mile^2

1 mile^2 = 2.58999 Km^2

area in Km^2 = 0.0182108 Km^2

area in m^2 = 18210.8 m^2

area in ha = 1.8210 ha
