Kaylie Mccarty · Answer 1

Second option: The area increases by 6 square units.

Step-by-step explanation:

A1 = ½ * 4 * 3 = 6 units²

A2 = ½ * 4 * 2 (3) = 12 units²

Increase: 12 - 6 = 6 units²

Alia Beasley · Answer 2

The area increases by 6 square units.

Step-by-step explanation:

The original area of triangle

A = 1/2 bh

a = 1/2 (4) * 3

6 square units

Now we double the height

A = 1/2 (4) * 6

A = 12 square units

The difference is 12-6 = 6 square units
