Answer:A = Lw (Area = length * width)

L = 2w (length is twice the width

A = 50

Step-by-step explanation:

We have variable values, so plug them in:

50 = 2ww

50 = 2w2

Divide both sides by 2:

25 = w2

Square root:

5 = w

So there's the width. Double that and you'll get the length.

P = 2L + 2w (perimeter equals the two lengths and two widths added together)

You know the length and width, so add them together twice--add two lengths together and two widths together to get the perimeter.
