Answer:
First, second, and fourth are true.
Explanation:
Ok, so let's get to it.
The first statement is true, since 6 * 4 = 24.
The second statement is also true, since the 4 triangles are the 4 sides.
The third statement is false since they aren't congruent since they don't have a consistent ratio.
The fourth one is true, since 24(2) + 18.4 does indeed equal to 66.4
The fifth one is false since only the base has an area of 24.
