The county animal park is shaped like a triangle. Two perpendicular sides of the park measure 2.3 miles and 3.4 miles.

What is the area of the animal park?

a. 3.91 mi²

b. 5.7 mi²

c. 7.82 mi²

d. 11.4 mi²

A. 3.91 m²

area of a triangle is (base x height) / 2

b=3.4

h=2.3

(2.3) (3.4) = 7.82

7.82/2=3.91

**the height of this triangle would be one of the sides because it is a right triangle (sides meet and form perpendicular lines, or a 90° angle)
