Question

the perimeter of the top of a desk is 54 inches . if the length of the desk is 15 . what is the is the width of the desk

Answer 1

12 is the width because a desk is usually a rectangle so if the length on one side is 15 the other is also 15. So 15 + 15= 30. Then if you subtract 55 by 30 you get 24. Nd there's two side so if u do 24 divided by two u get 12

Answer 2

`Perimeter=2width+2length\\\\ length=15\\\\ perimeter=54\\\\ 54=2*15+2width\\\\ 54=30+2width\ \ \ | subtract\ 30\\\\ 24=2width\ \ | divide\ by\ 2\\\\ width=12inches`
