# Perimeter of an L-Shape

Learning video 93 · Geometry · Grade 4 · 0:35

## Read the story

This shape looks like an L. We are looking for its perimeter.

We slide the short sides outwards. That makes a rectangle of 6 and 4 centimeters.

The perimeter stays the same: 6 plus 4 plus 6 plus 4 is 20 centimeters.

**An L-shape fits into a rectangle of 8 cm and 5 cm. What is its perimeter?**

## Answer and working

Correct! 8 plus 5 plus 8 plus 5 is 26 centimeters.

`8 + 5 + 8 + 5 = 26`
