Question

Please help me and thank you!

Answer 1

54 feet would be exact i think dont take my word for it.

Answer 2

Givens

Area: x^2 - 80x - 1500

Width: x - 30

Length: ??

Solution

x^2 - 80x - 1500 will factor

Area = (x - 30) (x - 50)

Length = Area / width

Length = ( (x - 30)(x - 50) ] / (x - 30)

Length = x - 50

Comment

You could say that the width = 30

And the length = 50

But I don't think that is what you are asked for.
