The area of a parallelogram is 30cm & # 178;, and the area of a triangle with the same base and height is () CM & # 178

The area of a parallelogram is 30cm & # 178;, and the area of a triangle with the same base and height is () CM & # 178

The area of a parallelogram is 30cm and the area of a triangle with the same base and height is 15cm;
Parallelogram area = bottom * height triangle area = (bottom * height) / 2

1. The bottom of a triangle is 10 cm, the height is 6 cm, its area is () CM & # 178; the bottom of a parallelogram equal to its area and height is () cm
2. The area ratio of a triangle with equal base and height to a parallelogram is (), if the area of a parallelogram is 12cm & # 178;, the area of a triangle is () CM & # 178; . judge right or wrong. 3. Two disjoint line segments are parallel lines. 4. Only one group of paralleled quadrilateral is trapezoid. 5. Two identical right triangles can only be combined into rectangles. 6. Two rectangles with equal perimeter have a certain area

The area of a parallelogram is 30cm2, which is the same as that of a triangle with the same base and height______ ．

30 △ 2 = 15 (square centimeter); answer: the area of the triangle with the same base and height is 15 square centimeter. So the answer is: 15 square centimeter
