The area increases by 3 square units.
The area increases by 6 square units.
The area increases by 12 square units.
The area does not change.
help what is it?

Answer 1

The area increases by 6 square units.

Explanation:

The formula for the area of a triangle is base times height divided by two.

So, first solve 3 times 4 divided by 2.

Simplify 4 and 2 and you get 3 times 2 which = 6

Then Mark doubles it right?

So do 6 times 2 and you get 12

The first answer is 6, so it increased by 6.

I hope this answer helped. Sorry if I was wrong.
