长+宽=336÷2=168
长-宽=14
所以
宽=(168-14)÷2=154÷2=77厘米

求一个矩形的宽度,它的周长是336厘米,宽比长少14厘米。

一个长方形(矩形)的周长是336,长比宽大14,求它的宽
(336/2-14)/2=77cm

题目是求矩形的宽:提供的条件为:周长336cm,宽比长少14cm.
设宽为x,则长为x+14,
336=x+x+(x+14)+(x+14)
x=77(cm)

长方形的周长是336CM,长-宽=14CM
设宽为X (CM),则2X+2(X+14)=336
解得:X=77 (CM)
即长方形的宽为77CM

一个矩形的周长是336厘米,宽比长少14厘米,求该长方形的宽是多少?
设宽是x,则长度为(x+14),
x + (x + 14) = 336/2
x = 77
即:该长方形的宽是77厘米

长+宽=336÷2=168
长-宽=14
所以
宽=(168-14)÷2=154÷2=77厘米
