Given a square with an area of 16 square inches, find the perimeter of the square and the area of the regular hexagon of the same perimeter.

A guy wire for a suspension bridge runs from the ground diagonally to the top of the closest pylon to make a triangle. We can use the Pythagorean Theorem to find the length of guy wire needed. The square of the distance between the wire on the ground and the pylon on the ground is 423,500423,500 feet. . The square of the height of the pylon is 12,100 feet.

Find the remaining sides of a 30°–60°–90° triangle if the longest side is 9.
