Question

A triangle has a base of 4 units and a height of 3 units. Mark draws the triangle again but doubles the height. How does the area of the triangle change?

A. The area increases by 3 square units.
B. The area increases by 6 square units.
C. The area increases by 12 square units.
D. The area does not change.

Answer 1

Answer:the correct answer is b

Explanation:

Answer 2

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.
