A tetrahedron has 4 triangular faces. If the total surface area is 20 m², the area of one face can be calculated by dividing the total surface area by the number of faces.
\[
\text{Area of one face} = \frac{\text{Total Surface Area}}{\text{Number of Faces}} = \frac{20 \, \text{m}^2}{4} = 5 \, \text{m}^2
\]
So the area of one face of the tetrahedron is **5 m²**.
\[
\text{Area of one face} = \frac{\text{Total Surface Area}}{\text{Number of Faces}} = \frac{20 \, \text{m}^2}{4} = 5 \, \text{m}^2
\]
So the area of one face of the tetrahedron is **5 m²**.
