I think it’s 3885
Because 6216 divided by 8 is 777, 777x5 is 3885.
I hope that’s right and answers your question
Answer:
L=10cm , W=30cm
Step-by-step explanation:
First use the given that W=10+2*L
Use P=2W+2L=80, substitute W in the perimeter formula
2(10+2L)+2L=80 and solve for L,
20+4L+2L=80 isolate variable L and combine like terms,
6L=80-20,
L=10, so W=10+2*10=10+20=30
The answer is 3.83 !
Hope it helped
