The area of a triangle is 5 / 6 square meters, the height is 2 / 3 meters, and the length of the bottom edge is how many meters? It is better to have pictures in the process of writing

The area of a triangle is 5 / 6 square meters, the height is 2 / 3 meters, and the length of the bottom edge is how many meters? It is better to have pictures in the process of writing

Triangle area = bottom length * height / 2,
therefore
Bottom length = (5 / 6) * 2 / (2 / 3) = 2.5m

The area of a triangle is 48 square decimeters, the length of its bottom is 120 cm, and how many decimeters is its height?

120 cm = 12 decimeters
Set the height to x decimeters
12X÷2=48
12X=48×2
12X=96
X=96÷12
X=8
A: the height is 8 decimeters

In triangle ABC, DC = 2bd, EC = 3aE. If the area of triangle ABC is 120 square decimeters, what is the area of triangle ade?
E is between AC and D is between BC

∵DC=2BD
Ψ s △ ADC = 2 s △ abd (equal height of two triangles)
∴S△ADC=120÷(1+2)×2=80
Similarly, s △ DCE = 3 s △ AED
So s △ AED = 80 △ (1 + 3) × 1 = 20
