Answer:
8 square units
Explanation:
The base is on a horizontal line. The points are 7-3 = 4 units apart.
The side perpendicular to the base is a vertical segment 6 -2 = 4 units long.
The area is ...
A = 1/2bh
A = 1/2(4 units)(4 units) = 8 units²
The area of the triangle is 8 square units.
__
It is effectively half of a square that is 4 units on a side. 1/2(4²) = 8.
