Mx = (Ax + Bx)/2 My = (Ay + By)
6 = (7 + Bx)/2 5 = (10 + By)/2
12 = 7 + Bx 10 = 10 + By
5 = Bx 0 = By
(5,0)
Answer:
21 kilometers
Step-by-step explanation:
Let the height be
. Then, the length of the base is
. The formula for the area is of the triangle is given by base*height/2. Therefore, the area of the triangle is equal to
, which is in turn equal to 441. Since
must be positive, then
, meaning that the height is
kilometers.
