| February 5, 2021 | education
The base b of the triangle is 10 decimetres.
The height h of this triangle is 5 decimeters.
The area of a triangle is calculated by the formula S = 1/2 * b * h.
Let’s find the area of this figure:
S = 1/2 * b * h = 1/2 * 10 * 5 = 25 dm2.
Answer: S of a triangle is 25 dm2.
