Add up the length of all sides - it's the outside
Well maybe I'll build a fence
Or maybe I'll take a walk around the block
I need to find the distance around the outside - that's good Perimeter's the outside - you just add
It's all around the outside - it's good Perimeter's the outside
Area means the inside
Cover the surface that's inside Measure the length and measure the width
And then you multiply
Well maybe I'll buy a new shag carpet Or maybe I'll make a quilt using squares
I'll just make sure - I multiply
The length by the width
Find square units inside
It's the area - that's good
The area's the inside - multiply The area's the inside - it's good Square units on the inside
Perimeter's the outside - you just add It's all around the outside - it's good Area's the inside - multiply
Square units on the inside
