Find the area of the composite figure and show your work anyone who shows work will be marked brainliest

Very messy but as you can see you first figure out how long the top is which is 23.

Then you split the larger shape into 3 rectangles and for each one figure out the area by multiplying length and breadth. 23*31 and for the middle rectangle you subtract 12 from 31 to get 19. 19*23 and 23*31 again.

Adding the area up 713+437+713=1863m^2

Alright.

We have to split the figure up. For instance, we can make it so we have 2 squares up top and one rectangle on the bottom.

Let's find the area of the squares.
We know that the width of the left square = 12 m and that the length of the right square = 23 m. 

so we have 12m * 23m = 276 m^2. But there are two squares, so let's add another value (or multiply by 2).
276m + 276m = 552 m.

Now, let's solve for the rectangle. In order to find the height, use the width value from the left square, 12 m, and subtract from 31 m.
31 - 12 m = 19m

We already know the width, so let's use the area formula!
19m * 69m = 1,311m^2

Now, let's add up the values for the final answer
1,311 + 552 = total area of 1,863m^2
