Answer:
Length of L is 50/8
_______________
Length of n is 10
_______________
length of m is 150/8
Step-by-step explanation:
put 1/3m instead of L.
as the perimeter is 65,
1/3m+ 1/3m+m-15+m=65
2/3m+2m=50
8/3m=50
m= 50*3/8=150/8
m=18.75
L=150/8* 1/3=150/24= 50/8
n= 50/8+ 150/8-15
n= 200/8-15= 80/8= 10
Hope it helps!
