Answer: B. 864 units²
Step-by-step explanation:
First, we will find the area of the bottom base square.
L * W = A
16 units * 16 units = 256 units²
Next, we will find the areas of the triangles. Since there are four congruent triangles, we will find the area of one and multiply it by 4.
[tex]\frac{\text{B}\;*\;\text{H}}{2}[/tex] = A
[tex]\frac{\text{16 units}\;*\;\text{19 units}}{2}[/tex] = A
[tex]\frac{\text{304 units}^2}{2}[/tex] = A
152 units² = A
-
152 units² * 4 = 608 units²
Lastly, we will add the two values together to answer this question.
608 units² + 256 units² = 864 units²
864 units²
