Answer:
A = 387
Step-by-step explanation:
An easy way to do this would be to divide them into 3 rectangles, like in the pic I have attached.
Then, solve the area of each rectangle, and add them.
The formula for area for a rectangle is length times width.
The equation for the big rectangle is 10 times 24 = 240
The equation for the middle rectangle is 6 times 19 = 114
The equation for the small rectangle is 3 times 11 = 33
Now, to find the area of the whole shape, we have to add the areas of the 3 rectangles:
240 + 114 + 33 = 387
