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
