Answer:
Explanation:
The rectangle in the middle has an area of 30 because it is a 3x10.
The triangles each have an area of 6 because they are a 3x4 and the forumla to find it is .5(bh) which is .5(12)=6. There are 2 of them so the total area of the triangles add up to 12.
Add the area and get 42. 30+12=42
