Using the formula for the area of a triangle, , write an expression for the area of ΔABC. Base your answer on the work you did i

Montano1993 [528]

Answer:

$Area = \frac{1}{2} * AC * D$

Step-by-step explanation:

From the complete question, we have:

Length D to be perpendicular to side AC

So, the area of the triangle is:

$Area = \frac{1}{2} * Base * Height$

Since:

Length D is perpendicular to side AC

Then:

$Base = AC$

$Heigjt =D$

So:

$Area = \frac{1}{2} * AC * D$
