Landen Wade · Answer 1

The area of a triangle is calculated by multiplying the height times the base and the dividing it by two. the area of the original triangle would be 4*3/2, which is 6. with the height doubles, the area would be 4*6/2, which is 12. 12/6 is two, so the area of the triangle doubles.
