Write a system of equations ________
________
Solution: length _____ width ______

Respuesta :

width -w
length l= 2*w+5
perimeter P=2w+2l, 52=2w+2l

system of equations:
52=2w+2l  ------> 26 =w+l  (1)
 l= 2*w+5    (2)

substitute  value of l from second equation into the 1st
26=w+2w+5
26=3w+5
21=3w
w=7

l=2w+5,  l=2*7+5, l=19

Answer:
system
52=2w+2l
 l= 2*w+5 

length 19 ft, width 7 ft
