Trapezoid.

A = (5+4) x 11/2 = 49.5

Long side is 11 in. bottom base is 4 in
Correct? Or you need more info?

Where did the 5 come from?

Is the long side one of the parallel sides?

Is the long side one of the parallel sides ? YES

Where did the 5 come from? Slanted top.

I don't understand a slanted top. Are there any perpendicular lines in the figure? Any angle measures given?

I figured it out. Thanks.

To determine if the given information is sufficient to calculate the long side and bottom base of a trapezoid, we need to understand the properties of a trapezoid.

A trapezoid is a quadrilateral with at least one pair of parallel sides. The formula to find the area of a trapezoid is:

A = (b1 + b2) * h / 2,

where A represents the area, b1 and b2 are the lengths of the parallel sides (also called bases), and h is the perpendicular height of the trapezoid.

Given in the question:

A = (5 + 4) * 11 / 2 = 9 * 11 / 2 = 49.5.

The product of (5 + 4) * 11 divided by 2 equals 49.5, which is the area of the trapezoid.

However, we still need more information to determine the lengths of the long side and the bottom base. The area alone doesn't provide enough information to calculate each side's length independently.
