Question

A triangle and the coordinates of its vertices is shown in the coordinate plane below. Enter the area of this triangle in square units, rounded to the nearest tenth. square units

Answer 1

22 units²

Explanation:

1/2b*h=area

You can either count the units or use the distance formula.

`d = \sqrt{ {(x2 - x1)}^(2) + {(y2 - y1)}^(2) }`

b = 4 units

h = 11 units

area = (1/2*4)*11 = 22 units²
