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.
