Explanation:
The perimeter ( P) of a rectangle in terms of its height ( h) and width ( w) is.
#color(red)(bar(ul(|color(white)(2/2)color(black)(P=2h+2w)color(white)(2/2)|)))#
#"here "P=54" and "h=12#
#rArr54=(2xx12)+2w#
#rArr54=24+2w# subtract 24 from both sides of the equation.
#54-24=cancel(24)cancel(-24)+2w#
#rArr2w=30# divide both sides by 2
#(cancel(2) w)/cancel(2)=30/2#
#rArrw=15#
#rArr"the width of the frame "=15" inches"#
