Am i correct let me know if i did a mistake

  Check your addition. Units need to be supplied with your final answer.

Step-by-step explanation:

It appears you want the total area of the figure. You have correctly figured the area of the rectangle and the dimensions of the triangle.

You have correctly figured the area of the triangle, but your final total is off.

___

It is helpful to the casual reader (and perhaps your teacher) if you identify what each calculation is supposed to be doing.

The formula for the area of a triangle is

  A = (1/2)bh

It is all one product. I would write it as (1/2)(19)(12) = 114. I would actually compute it as 19·6 = 114.

___

In cm^2, the area of the rectangle is ...

  rectangle area = L·W = 22·17 = 374

The area of the triangle is ...

  triangle area = (1/2)bh = (1/2)(19)(12) = 114

The total area is

  total area = rectangle area + triangle area = 374 + 114 = 488 . . . . cm^2

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
