A rancher has a rectangular 40 acre piece of property fronting a highway. He wants to put a barbed-wire fence along his road frontage. How much fence does he need if his property depth is 1,200’?
An acre is a surface measure, used in agriculture in several countries. According to the country and the time, it is equivalent to several surfaces. We will use the following conversion: 1 acre = 43560 feet ^ 2 Thus: 40 acre = 1,742,400 feet ^ 2 The area of the rectangle is: 1,742,400 = (1,200) * (x) Clearing the other dimension we have: x = (1742400) / (1200) x = 1452 feet Answer: He needs 1452 feet of fence.
