Question

a planer is designing a rectangular park the length needs to be at least 200feet and the width needs to be at least 500 feet however the perimeter cannot exceed 1,800feet if the system describes the possible lengths (l) and widths (w) of the park which of the following dimensions are possible

Answer 1

i say B

Answer 2

How ?

Answer 3

It doesn't even have the required minimum width of 500.
It's the first option that you should eliminate.

Answer 4

never mind C i think

Answer 5

Maybe yes, maybe no.
Unless you tell me why you think it is C, I don't give a rats retriceof what you pick..

Answer 6

well 600 +500 is below 1800 and the w stays at 500

Answer 7

Very good try. But its wrong; looks you're adding L + W, instead of 2L + 2W

Answer 8

First,look at the given conditions..
it says that\[1\ge200\]\[w \ge500\]\[2l+2w \le1800\]\2(l+w)\le1800\]\[l+w \le900\]we must fulfill this condition

Answer 9

option B(length=200 and width=400)\[w \ge500\] should be eliminate first bcoz is does not fufill the condition..

Answer 10

Lets look at the given conditions again
it says that\[2l+2w \le1800\]\[l+w \le900\]

Answer 11

now,i will need u to add l+w in each options..

Answer 12

The maximum value u can reach is 900 or less than 900

Answer 13

The option which exceeds more than 900 should be eliminated..
