A rectangular garden that is w ft wide is enclosed by 120ft of fencing. How long is the garden??
All I need is an expression. I know that u can't solve this ptoblem because it doesn't give you enought information.
P = 2w + 2l
120 = 2w + 2l
I had te same thing!! But at the back of te book the answer is (60-w) ft. And I am confused how yet got it!
Since 120 is the measurement of all four sides of the rectangle, then 60 is the distance around two adjacent sides.
That's why the length equals 60 minus the width.
