Step-by-step explanation:
The figure is broken into different shapes so you find the area of each shape shown and add them up!
Step one: find the area of the triangle. 1/2*base*height* The base is 3 and the height is 4. it will be 6. This applies to the second triangle on the bottom as well. The total of both triangle is 12.
Step two: find the area of the rectangle.base*height. All you have to do is 10*3 which is 30.
Step three: now add up all the areas you got. 30+12. which is 42.
