- Juan was asked to create a tarpaulin for the school program. Due to restrictions in the printing machine and the costs, the tarpaulin can only have 46.5 square inches of printed area. Holes for ropes were placed, in order to hang the tarpaulin. Because of these holes, there was a 0.1 meter margin at the top and bottom, and 0.05 meter margin on the sides. If the total area of the tarpaulin is minimized, what will be its dimensions?arrow_forwardA woman 6 feet tall walks at the rate of 3 feet per second away from a streetlight that is 15 feet above the ground.
