Question

Find the area in square units of ▱ABCD.

5

6

Quadrilateral A B C D has four labeled vertices and two line segments.

1. The left side starts at vertex A, goes up and to the right and ends at vertex B.
2. The top side is horizontal, starts at vertex B on the left and ends at vertex C on the right.
3. The right side starts at vertex C, goes down and to the left and ends at vertex D.
4. The bottom side is horizontal, starts at vertex D on the right and ends at vertex C on the right.
5. The first line segment goes from vertex A and ends at vertex C. The second line segment goes from vertex B, intersects segment A B at a right angle, and ends at D.
6. The length of segment A C from vertex A to the intersection is 6. The length of segment B D from vertex B to the intersection is 5.

Answer 1

Area A = 0.5AC·BD = 0.5·12·10 = 60 squarer units.
