Answer:
12 ft²
Step-by-step explanation:
The figure is composed of 2 triangles.
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
A of upper triangle = [tex]\frac{1}{2}[/tex] × 4 × 3 = 2 × 3 = 6 ft²
A of lower triangle = [tex]\frac{1}{2}[/tex] × 4 × 3 = 2 × 3 = 6 ft²
Thus
area of figure = 6 + 6 = 12 ft²
