The height of parallelogram is 51.87 cm Step-by-step explanation: Let The height of a parallelogram = a cm Then The base of a parallelogram = 3a cm So by the given condition 3a×a = 897 3a^2 = 897 a^2 = 897/3 a^2 = 299 a = 17.29 So the height of parallelogram = 3×17.29= 51.87 cm Plugging variables into an expression is essential for solving many algebra problems. You can see this most easily when you draw a parallelogram on graph paper or look at the diagram below. If the side that was 5 units long was chosen as the base instead, the height would be 4.8 units. The height is the distance from the base straight up to its parallel side. The area of a parallelogram is expressed in square units. The base is the length of the long, flat side on the bottom. problem and check your answer with the step-by-step explanations. A parallelogram whose angles are all … A height can be drawn outside of the parallelogram, as long as it is drawn at a 90-degree angle to the base. 4. The rectangles Tyler and Elena created through decomposing and rearranging the parallelogram are identical; they have the same side lengths. 6. The line labeled the height is the diagonal side, not a line perpendicular to the base. Perimeter = 2 × (12 cm + 6 cm) = 2 × 18 cm = 36 cm Diagonals of a Parallelogram To be a parallelogram, the base and top sides must be parallel and congruent, and so must the left and right sides.
