Answer: Length is 15 and width is 91
Step-by-step explanation:
If the length is 16 more than 5 times the width, that means:
let's say
x=length
y=width
2x+2y=212
If the length is 16 more times than 5 times the width, that means
y=5x+16
now we can substitute all y's for 5x+16:
2x+(5x+16)2=212
=2x+10x+32=212
=12x+32=212
=12x=180
x=15
If the length is 15, the width is
15*2+2y=212
=30+2y=212
=182/2
y=91
Answer:
width 91 length 15
Step-by-step explanation:
2l+2w=212
l=5w+16
2l+2w=212, l=5w+16
substitute
2(5w+16)+2w=212
12w+32=212
12w=180
w=15
L=5w+16
L=5(15)+16
L=91
