Question

I don't know what to do next

Answer 1

Question and work

Answer 2

You have your answer, 3m by 20m. The question is asking for the size of the rectangle, not the area, which is why you aren't finding 60m^2 as the answer. You already found the answer, A

Answer 3

no the answer key isnt a tho

Answer 4

Which answer does the key specify?

Answer 5

b

Answer 6

That would be the maximum area, however, it would not make a rectangle, it would make a trapezoid.

Answer 7

so what do i do next

Answer 8

I'm not entirely sure. Only A would make a rectangle by using the entirety of the garden wall; the others could make a rectangle, but parts of the garden wall would be hanging off to the side.
I'd wait to see if anyone else can explain this.

Answer 9

oh shoot i got a test tomrrow

Answer 10

Honestly, I think that the answer key is wrong. C and D obviously can't be the answer, they add up to more than 26 meters. That leaves A and B, but B would be a trapezoid, so it is also invalid.
