Calculate the area of the right triangle that has vertices at A (525,260),B (725,260), and C525,-10).

adoni [48]

The correct answer to this question is this one: So, the area is 108,000 square units

Distance of point A to point B = 800 (base)
Distance of point A to point C = 270 (height)
Distance of point B to point C = 336.006 (hypotenuse)

So, in finding the area of a triangle:
Area = 1/2 * b * h
Area = 1/2 * 800 * 270
Area = 108,000

So, the area is 108,000 square units
