Question

area of triangles and parallelograms
what is the area of parallelogram abcd?
16 square units
20 square units
24 square units
28 square units

Explanation:

Step1: Identify base and height

From the graph, assume base \(DC\). Counting the grid - points, \(DC = 5\) units and the height (perpendicular distance from \(A\) to \(DC\)) is \(4\) units.

Step2: Apply area formula

The area formula for a parallelogram is \(A = base\times height\). So \(A=5\times4\).

Step3: Calculate the area

\(A = 20\) square units.

Answer:

20 square units
