Perimeter of rectangle 14 m by 9 m

Step by step

The question

Question: find the perimeter of a rectangle 14 m long and 9 m wide.

1 Find every side

The perimeter is the way all around the edge.

We add every side.

The top is the same as the bottom: 14 m.

The right side is the same as the left: 9 m.

2 Add all the sides

Walk around and add: 14 + 9 + 14 + 9.

14 plus 9 is 23.

The other two sides make 23 too.

23 plus 23 is 46.

So the perimeter is 46 m.

Let's look back.

First: find every side.

Last: add all the sides.
