Question

Triangle ABC has vertices A(0,7),B(5,-5),and C(10,7). Find the area of triangle ABC?.​​

Answer 1

Answer:

60 units²

Step-by-step explanation:

A = ½bh

Let the horizontal line AC be the base which has a length of 10 along the line y = 7

The vertical distance between this line and point B is 7 - (-5) = 12

A = ½(10)(12)
