The perimeter of a college athletic field is 100 meters and the length is 18 m more than the width. How do you find the length and width. How would I find the answer?
Length = 34m
Width = 16m
I would form an algebraic expression from the information given:
Let length of field be represented by
We are told that perimeter is 100m, so
which simplifies to:
by dividing both sides by 2
The other info tells us that length,
Then solve the equations simultaneously (I have used substitution):
Then substitute back into either equation to obtain
Double check by making sure
Hope this helps!
