Ответ:
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.
