The diagram shows nine identical squares inside a rectangle. The length of the rectangle is 18 cm . Work out the width of the rectangle. Your final line must say, width=...

width  2 cm

Step-by-step explanation: INCOMPLETE QUESTION

DIAGRAM IS MISSING

We have just one possibility  of such structure

We have one row of 9 squares, each of them having 2 cm  length so 9 times 2  is 18 cm and of course the height of the rectangle will be 2 cm. Then squares of  2 x 2 cm² fit in a rectangle of 18 cm length and 2 cm wide.

We can choose a configuration of 9 squares in three equal rows, in that  way we get three sides of 6 cm length, and to form a square we need 6 x 3 = 18 cms of height and the surface becomes a square and we lose the initial condition from problem statement " identical squares inside a rectangle"

idk bring the function back   im not smart
