Answer:

8 units²

Step-by-step explanation:

The area (A) of a triangle is calculated using the formula

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = LK = 7 - 3 = 4 units

and h = J → x- axis = 4 - 0 = 4, hence

A = [tex]\frac{1}{2}[/tex] × 4 × 4 = 8 units²
