Question

A wire is first bent into the shape of a square. Each side of the square is 6cm long. Then the wire is unbent and reshaped into a rectangle. If the length of the rectangle is 8 cm, what is its width?

Answer 1

First let's calculate the perimeter of the square so that way we know the entire length of the wire

does that sound good to you?

Answer 2

ya

Answer 3

if one side of the square was 6 cm long

what is the perimeter?

remember, since a square has 4 sides that are all equal

perimeter = side + side + side + side

or perimeter = 4 * side

Answer 4

24

Answer 5

yay good!

Answer 6

now we're forming this rectangle from 24 cm of wire

Answer 7

The perimeter of a rectangle is going to be the same as the square because we just changed the shape

Answer 8

now we want to find the missing side
