16 can be approximate width and length which is doubled can be 32, multiply and get 512 which is close to 500m^2, you can also try other close related approximate solutions such as 15 and 30, and more, but closest approximate whole numbers would be *16 as width and 32 as length*
The approximate width of Alice's backyard is 22.36 in.
Let l be the length of the rectangle and w be the width. l = 2w A = 1000 m2 = l*w 1000 m2 = 2w *w 500 m2 = w^2 √500 m2 = √w^2 w = <span>22.360679775 in or 22.36 in</span>
the answer is true. if you have square with 4 cm on all sides and double it, it will become 8 cm on all sides. the first square has a perimeter of 16 and the second square has a perimeter of 32. therefore the perimeter doubles.
