First find the area of the whole square. Even the part that isn't part of the area. Then find the area of the spots that aren't part of the shape. Then subtract that area from the area of the whole thing.
15×18=270
(9x12)+(4×5)=128
270-128=142
Area= 142ft^2

The solution for s in the given equation is 
The question seems to be incomplete
Here is the complete question:
Solve for s in this equation
Depreciation.
To solve for s, that means we should make s the subject of the equation
From the given equation,
To solve for s, first multiply both sides by n to clear the fraction
We get

Then,

Now, add s to both sides


Then, subtract nD from both sides

∴ 
Hence, the solution for s in the given equation is
