INTRO
โ€”
When weโ€™re asked to find the area of a quadrilateral, what weโ€™re really looking for is the amount of space inside the boundaries or sides that connect to make the shape.
Letโ€™s imagine we want to build a small field in a Minecraft world and need to figure out the amount of land (area) in a 3 ร— 5 field.
We can start with a strip of land that has blocks of grass.
And then we just need to copy this row times.
Now, we have rows of grass blocks, giving us a total of blocks.
This is area ๐Ÿ˜ฎ. By multiplying the length by the width, we get the amount of space inside the sides of a rectangle.
Multiplying a shape's length (or base) by its width (or height) is a pattern youโ€™ll notice when solving for the area of different quadrilaterals:

How to Find the Area of a Quadrilateral

Shape:

Step 1. Identify the length & width of the rectangle.

Step 2. Multiply the length by the width.

Step 1. Identify the side length of the square.

Step 2. Square the side length.

Remember, all the sides of a square are equal to each other, so .

Step 1. Identify the base and height of the parallelogram.

Step 2. Multiply the base by the height.

Remember, a parallelogram can be rearranged to form a rectangle.

Step 1. Identify diagonal/cross lengths of the rhombus.

Step 2. Square the diagonal/cross lengths.

Step 3. Divide by .

Remember, a rhombus can be rearranged to make a parallelogram.

Step 1. Identify the base lengths and height of the trapezoid.

Step 2. Add the base lengths.

Step 3. Multiply the sum of the base lengths by the height.

Step 4. Divide by .

Remember, two trapezoids can be rearranged to make a parallelogram.
