The area of a parallelogram is equal to the area of a triangle. The height of the triangle is 5cm. If the two figures have the same base (底), find the height (高) of the parallelogram (平行四邊形).
Let the height of the parallelogram be h cm and their base be b cm.

✔ 最佳答案
Area of paraellogram = b*h cm^2Area of triangle = 1/2 (b)*(5) = 2.5b cm^2
As their area are the same
Therefore, b*h=2.5b
h=2.5cm
The height of parallelogram = 2.5cm

Triangle has area = (1/2)(5cm x bcm)
Parallelogram has area = bcm x hcm
Area of Triangle & Parallelogram are equal.
therefore:
(1/2)(5cm x bcm) = bcm x hcm
2.5b = bh
除b)
.h=2.5cm
Parallelogram has area = bcm x hcm
Area of Triangle & Parallelogram are equal.
therefore:
(1/2)(5cm x bcm) = bcm x hcm
2.5b = bh
除b)
.h=2.5cm
