Answer:

18 mi²

Step-by-step explanation:

Using the formula:

[tex]A = \frac{hb}{2}[/tex]

[tex]A = \frac{4.5*8}{2}[/tex]

A=36/2

A=18

Units will be mi² since it is area

Answer:

A = 18 mi²

Step-by-step explanation:

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 )

here b = 8 and h = 4.5 , then

A = [tex]\frac{1}{2}[/tex] × 8 × 4.5 = 4 × 4.5 = 18 mi²
