Answer:
B. 1395 sq. units
Step-by-step explanation:
Since the shape is an octagon, it is also composed of 8 triangles. If you solve the formula for the area of a triangle with those numbers and multiply it by the amount of sides you will have the total area.
A=2(1+[tex]\sqrt{2}[/tex])a²
A=2(1+[tex]\sqrt{2}[/tex])17²
A=2(1+[tex]\sqrt{2}[/tex])289
A≈4.83×289
A≈1395.87
A≈1395 units²
The option that fits this is B. 1395 sq. units
