The amount of fence a farmer needs to create a garden with width w and length l is f = 5w + 21.
Nonamiya [84]

The formula that represents l in terms of f and w is l = (f-5w)/2

<h3>Subject of formula </h3>

This is way of representing a variable with other variables in an expression, Given the expression that represent the amount of fence a farmer needs to create a garden with width w and length

f = 5w + 2l

Make l the subject of the formula

2l = f - 5w

Divide both sides by 2

2l/2 = (f-5w)/2

l = (f-5w)/2

Hence the formula that represents l in terms of f and w is l = (f-5w)/2
