Mrs. Clayton is walking along a trail that is shaped like a triangle.
The first side of the trail is 3.89 kilometers long. The second side
of the trail is 4.19 kilometers long. The third side of the trail is
0.94 kilometer long. About how long is this trail?
Responses
A 9 km9 km
B 20 km20 km
C 5 km5 km
D 4 km
To find the length of the trail, you need to add together the lengths of all three sides of the triangle.
3.89 km + 4.19 km + 0.94 km = 8.02 km
So the approximate length of this trail is 8 km.
The correct answer is (D) 8 km.
