24.The diagonals determine equilateral triangleswith sides equal to half the length of eachdiagonal, or 6 inches. So ef6, and ef3.Then a3(e) or 33, so cd33. Then theperimeter of the rectangle is 2(6)2(3333)or 1212332.78 inches.25.Each side has measure 2546or 8. The length of a diagonal is 2 times as long as a side of the square.So the measure of a diagonal is 8126.96.36.199x4xy3(x)y3(4) or 43z6Each leg of the 45°-45°-90° triangle has length x,or 4. Then CB42. So, the perimeter of ABCDis 43644268434224, or about 36.59 units.27.Graph Aand B.ABlies on a horizontal gridline ofthe coordinate plane. Since PBwill beperpendicular to AB, it lies on a vertical gridline.AB4(3)7ABand PBare congruent, so PB7. Point Phasthe same x-coordinate as B.Pis located 7 unitsabove B. So, the coordinates of Pare (4, 17) or(4, 8).28.Graph Gand H. If GHis the diagonal of a squarewith vertices P,G, and Hthen the other diagonalis perpendicular to and bisects GH.GHlies on a
