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

180 in

Step-by-step explanation:

Because if you multiply 15×12 it gives you 180

452,489 to the nearest thousand is 452,000

1/4 because there is 4 grades.
