Perimeter And Area Of Rectangles, Triangles And Compound Shapes
Gbogbo ọrọ náà
Perimeter is the distance around the edge of a shape; area is the amount of surface it covers. For rectangles, triangles, parallelograms and trapezoids there are simple formulas, and any awkward shape can be split into these familiar pieces.
In this lesson you will calculate the perimeter and area of rectangles, triangles, parallelograms and trapezoids, and handle compound shapes by breaking them into parts you can already measure.
