Respuesta :

the answer is 1,920 inches

Answer:

[tex]1920 in^2\\[/tex]

Step-by-step explanation

Number of triangle in octagon [tex]= 8\\[/tex]

Area of one triangle [tex]= \frac{1}{2} bh\\= (0.5)(20) (24)\\= 240 in^2\\[/tex]

Area of eight triangle = Area of Octagon

[tex]= 8 * 240 in^2\\= 1920 in^2\\[/tex]
