A parallelogram and a triangle have the same area and the same length at the bottom. If the height of the triangle is 6cm, the height of the parallelogram is () cm?

A parallelogram and a triangle have the same area and the same length at the bottom. If the height of the triangle is 6cm, the height of the parallelogram is () cm?

three

The area of a parallelogram is 8 square centimeters larger than that of a triangle with the same base and height. What is the area of a triangle? What is the area of a parallelogram

The area of parallelogram = sh, the area of triangle = SH / 2
So the area of a triangle with equal base and equal height is half of that of a parallelogram
Triangle area = 8, parallelogram area = 16

The area of a triangle is 8.1 square centimeter, and the area of a parallelogram with the same base and height is () square centimeter

The area of a triangle is 8.1 square centimeter, and the area of a parallelogram equal to its base and height is (16.2) square centimeter
Because, triangle area = bottom × height △ 2
In other words, the area of a triangle is half of that of a parallelogram with the same base and height,
Therefore, 8.1 × 2 = 16.2 square centimeter

A triangle with a base of 4cm and a height of 5cm is enlarged by 3:1, and the area of the figure is () square centimeter?
emergency

The area ratio is the square of the similarity ratio
The area of the original triangle is 10 square centimeters
3: 1 zoom in
The area becomes 90 square centimeters
A triangle with a base of 4cm and a height of 5cm is enlarged by 3:1, and the area of the figure is (90) square cm
