Measurement post

WALT:Find the perimeters/areas of common shapes, and limits of answer.


To find the perimeter of a shape I add all the measurements(length and width) together and make sure I add the unit of measurement to the number.

To find the area of a shape I multiply the length of the shape by the height of the shape e.g length x height. I make sure I add the unit of measurement to the number.

Example:A rectangle is 3 cm by 7 cm.
Perimeter: 3 cm + 3 cm + 7 cm + 7 cm=20
Area: 3 cm x 7 cm=21
