7. The Area Triangle

To understand the area of the triangle, it's required that one first understand the fact that if a rectangle that gets sliced diagonally from its bottom left corner to its top right corner or vica-versa, it will create two equal triangles that exists on opposite sides. This would then help one understand that in order to get the total area of the triangle, it would be required that they work out the total box area of the triangle using its width and height and then dividing that result by 2 because each triangle would form as half the total area of the rectangle's total area. This understanding then concludes to the fact that in order to work out the area of a triangle, it would be required that one box the triangle first in order to measure its total width and height and then dividing their multiplication quotient by 2 in order to end up with a result of the triangle's area.

Measurement Formula: Triangle (height × base) ÷ 2
