Answer: 8 meters by 20 meters
Im this case, when you have a rectangle, you can use the equation 2a*2b to give you the perimeter and the formula a*b to give you area. To get an area of 160, you can use the numbers 8 and 20, meaning one side is 8 meters and one is 20. Now, can see if 2(8) + 2(20) gives us 56. 40 plus 16 is 56.
