Perimeter of a ball court is 84 meters. length i'd 6 meters longer then twice the width. what is l and w

Define x :

Let x be the width.
Width = x
Length = 2x + 6 


Formula :

Perimeter = 2(L + W)


Find x :

Given Perimeter = 84 
84 = 2 (2x + 6 + x) 
84 = 2(3x + 6)
84 = 6x + 12
6x = 84 - 12
6x = 72
x = 72 ÷ 6
x = 12m


Find Length and Width

Width = x = 12m
Length = 2x + 6 = 2(12) + 6 = 30m


The width is 12m and the length is 30m.
