Find the area of a triangle with vertices at D(2, 0), E(–1, 0), and F(2, –7).
1 answer:
Answer:
units²
Step-by-step explanation:
D and E lie on the x- axis and F is vertically below D
The triangle formed is right at D with legs of length 3 and 7
The area (A) of a right triangle is found using the formula
A = 
bh ( b is the base and h the perpendicular height )
here b = 3 and h = 7, hence
A = × 3 × 7 = units ²
