First of all, thanks for anyone who helps me with this 1. Find the perimeter of an Isoceles triangle that has base angles of 36 degrees and an area of 580cm sq. The given answer is 126.4cm. 2. A designer plan the top of a rectangular workbench to be four times as long as it is wide, and then determines that if the width is 2.5 ft greater and the length is 4.7ft less, it wouldbe a square. What are its dimensions?
