Environmental: A field has a legal land area of 100 acres with horizontal measurements being 800 feet by 5,445 feet. The 800-foot dimension is flat (horizontal), but the longer dimension has a gradual elevation change from 2006 feet to 2998 feet. Although the legal land area is 100 acres, the sloped surface area must be used when calculation fertilizer,pesticide, and seeding applications. What is the approximate area, in acres, for the sloped surface of the field? Calculating length of side for right triangle uses the Pythagorean Theorem: a2+ b2= c2
Area of rectangle = Length x Width 1 acre = 43,560 square feet
