Im watching Barney and friends spitting hot bars

Barney is a dinosaur from our imagination

And when he's tall

He's what we call a dinosaur sensation

Barney's friends are big and small

They come from lots of places

After school they meet to play

And sing with happy faces

Barney shows us lots of things

Like how to play pretend

ABC's, and 123's

And how to be a friend

Barney comes to play with us

Whenever we may need him

Barney can be your friend too

If you just make-believe him!

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
