A township has corners with the coordinates A(0, 0), B(7, 0), C(7, 5), and D(2, 5), where measurements are given in miles. Remembering that there are 5280 feet in one mile and that an acre is 43,560 sq. ft., find the area of the township to the nearest tenth of an acre.
What will be an ideal response?
