The other side is five feet less than twice the shortest side. The perimeter is 33 feet. Find the length of each side. http://www.youtube.com/watch?v=XXNWGPZVIJA Triangle Perimeter #2 (perimtri2.mp4) In an isosceles triangle, two of the sides have the same length. The other side is 10 cm less than twice the length of one of the equal sides. The perimeter is 46 cm. Find the measure of each side. http://www.youtube.com/watch?v=lYMNHYyafrA Triangle Perimeter #3 (perimtri3.mp4) In a triangle, the lengths of the sides are consecutive integers. The perimeter is eleven more than twice the shortest side. What is the perimeter? http://www.youtube.com/watch?v=DciJyWoUTXM
