Answer:

6 miles

Step-by-step explanation:
Area is :

[tex]A = \frac{1}{2} hb[/tex]  OR [tex]A = \frac{hb}{2}[/tex]
So base is :
[tex]b = 2 \frac{A}{h}[/tex]
Substituting values given:
b = 2 × (13.5÷4.5)
b = 2×3
b=6

Answer:

the length of the base= 6miles

Step-by-step explanation:

Area of triangle =1/2 *Base*Hight

Now we sub the values in the formula:

13.5 = 1/2 * (length of the base) * 4.5

length of the base = (2 * 13.5)/4.5

length of the base = 6 miles
