The top of the table is in the shape of an isosceles trapezoid with height 30 inches and bases 48 inches and 36 inches. what is the area of the top of the table?

To find the area of a trapezoid, we use the following formula:

1/2 * (b1 + b2) * h 

b1 and b2 are bases of the trapezoid and h is the height. Knowing this, we can substitute the values we know of the top of the table.

1/2 * (48 + 36) * 30

Now, lets simplify what is in the parentheses.

1/2 * 84 * 30

Next, let's get rid of the fractions 

42 * 30

Finally, let's perform the multiplication to get our final answer.

42 * 30 = 1260

Therefore, the area of the top of the table is 1260 inches².
