148.5 in^2
Step-by-step explanation:
First, get the area of the rectangle
A = 15*12
A = 180
Now the area of the triangle, with the base at 3.5
A = h b/2
A = 9 * 3.5/2
A = 15.75
Since you have 2 halves, add them together., 31.5
Substract 31.5 from 180

Answer:
600
Step-by-step explanation:
Just below the solid line, there is the remainder and just above the solid line, there is a multiple of 12.
The number with a negative sign is being subtracted to the above number.
The first subtraction is mentioned as
5496-4800=696, observe that 696 is just below the solid line.
Now, proceeding further in the same way, the number below the second solid line is 96 which is obtained when the number in the box is being subtracted to the above number 696.
Let the number in the box is
. So,


Hence, the required number in the box is 600.
