# Area on a Coordinate Grid Worksheets

How to Find the Area of a Shape on a Coordinate Grid? We know that area is the amount of space a shape covers. When it comes to finding areas of geometrical shapes, we can use the standardized formulae for each of these to find the area. But what if you have to calculate the area of a shape on coordinate grid? You can calculate the area of a rectangle by counting the number of units each side cover. It is all about counting those units out carefully. You can count the units to find the base and height of all three triangles and subtract them from the area of the rectangle. This works well for most quadrilaterals. As you move on to circles, we have a section for that too.

• ### Basic Lesson

Guides students through finding the area of given figures within a coordinate grid. Base (BC) can be found by subtracting the x-coordinates of the two points.

• ### Intermediate Lesson

Demonstrates how to use the box method for triangles and polygons. 1. Draw the smallest "box" possible which will enclose the triangle making sure the "box" follows the grids of the graph paper. 2. Number each of the parts of the box with a Roman numeral. 3. The area of each of the parts added together equals the area of the "box".

#### Fractional Thoughts

A mother asked her daughter," Would you like two whole apples or four halves ?" "Four halves, of course," was the reply. "Why? It's the same, isn't it? " "No, it isn't, if I choose whole apples I can't see if there's a worm."
