$2W = 200 - L$

condition (1) ... $W \ge 30 \implies 2W \ge 60 \implies 200-L \ge 60 \implies L \le 140$

condition (2) ... $L \ge 2W \implies L \ge 200-L \implies L \ge 100$

If a square is made, each side of the fence would have what dimension in feet given the 200 ft of available fencing?

Square that dimension. Recall $9 \text{ ft}^2 = 1 \text{ yd}^2$

In which grade level does one normally find this kind of equality question? I simply can't remember actually ever studying this kind of question type. Is there a name for this type of question i.e. equalities? I am still at a loss on how to calculate the 2nd question.

Thank you again.

Thank you again.

In my country, it's for Grade 11. Dunno how that applies to Western countries, though.In which grade level does one normally find this kind of equality question?

I'm in Jakarta presently . .. is that using an International curriculum (i.e. Cambridge/Oxford etc.) or the National Indonesian Curriculum (I see you are in Indonesia).In my country, it's for Grade 11. Dunno how that applies to Western countries, though.

200 ft of fencing form three of the four equal sides of the square with the fourth side being the side of the building.... I am still at a loss on how to calculate the 2nd question.

Each side of fence is $\dfrac{200}{3} \text{ ft}$

area of the square formed is $\left(\dfrac{200}{3}\right)^2 \text{ ft}^2$

remember you’ll need to convert square feet into square yards ... I supplied the conversion relationship in my initial post

The answer is supposed to be 493.8 . . . if I take (200/3)^{2} = 66.67 * 66.67 = 4444.4 then divide this number by 9 I get the answer . . . I was not remembering this step . . . boy my math muscles are weak. The difficulty to add insult to injury is that over here in Asia the imperial system is unfamiliar . . .

I see. I was wondering because your profile says that your location is in Jakarta but it has a Canadian flag.I'm in Jakarta presently . .. is that using an International curriculum (i.e. Cambridge/Oxford etc.) or the National Indonesian Curriculum (I see you are in Indonesia).

It's the National Indonesian Curriculum.
