Sorry, I am just dum, What would be the area of this triangle? It is in demos and that last line underlined was just added to complete the triangle or else there would be no bottom line for the triangle.

A = 5 units²

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = bh ( b is the base and h the perpendicular height )

here b = AC = 5 and h = AB = 2 , then

A = × 5 × 2 = 2.5 × 2 = 5 units²

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
