Answer:
400% area and 200% perimeter
Step-by-step explanation:
Given is a picture of a rectangle. (i.e. opposite sides are equal and all angles equal to 90 degrees)
We know for any rectangle with length l and width, w
Area of rectangle = lw and
Perimeter of rectangle = 2(l+w)
Suppose the side lengths are doubled
Now length = 2l and width = 2w
New ARea = [tex]2l*2w\\=4lw[/tex]
i.e. 400% times is the new area.
New perimeter = [tex]2(2l+2w) =4(l+w)[/tex]
New perimeter is 200% times the old perimeter.
