Question

Perimeter of a rectangle is 500 cm. How do you find the maximum area of the rectangle? What is the length and the width?

Answer 1

I think its solving system of equation but I am not sure. A=widthxlength. 500=2l+2w.

Answer 2

Did you learn derivatives yet?

Answer 3

No.

Answer 4

I got A=250w-w^2 so far. Idk where to go from there/

Answer 5

the max area of a rectangle would be a square
like, if you had a set perimeter of 20
you could have a rectangle like 1 by 9 which would give you an area of 9
but if you got it closer to a square like 5 by 5 it would give you an area of 25

so if a square had perimeter of 500, what would it's length and width be?

Answer 6

125?

Answer 7

yep :)

Answer 8

Thank you so much, I was stuck on that problem like forever.!

Answer 9

glad I could help :D
