Answer:
[tex]7.2 mi^2[/tex]
Step-by-step explanation:
A trapezoid is a plane shape and its area is given as;
[tex]A = \frac{1}{2} (a + b) h[/tex]
where a = top base of trapezoid = 1.2 miles
b = bottom base of trapezoid = 2.4 miles
h = height of trapezoid = 4 miles
Hence, the area of the trapezoid shaped park is:
[tex]A = \frac{1}{2} * (1.2 + 2.4) * 4\\\\A = \frac{1}{2} * 3.6 * 4\\\\A = 7.2 mi^2[/tex]
The area of the trapezoid shaped park is [tex]7.2 mi^2[/tex].
