The length of the swimming pool is, 230 centimeters in length, and 216 centimeters in width. How I got my answer.
I first divided 446÷2=223, then I subtracted 223-7=216, that's width. Now I realise that there is 7 remaining, so I added 223+7=230, that's length!!
So to double check my work I added the width and length together, 216+230=446.
I hope this helps!
