Answer:

30

- Note: all 5 triangles are the same

Step 1: calculate the area of 1 triangle

This can be done by multiplying two of the sides together. Since each one is a 4x3, the area of two triangles together is 12 (because it makes up a rectangle).

Then divide it in half to get an individual triangle. So, 12 divided by 2 is 6, meaning the area of each triangle is 6 (whatever unit you`re measuring by).

Then multiply it by how many triangles are in the entire shape. 6x5[triangles] is 30. The area is 30.
