(10yds)(3ft/yd) 30ft. Area lengthXwidth 30ftX160ft 4800ft2

It is: 4+5+3 = 12 feet

1/12th scale is a twelfth the size of the original. If for instance the model is of a bus that is 12ft tall, 36ft long & 8ft wide, the model would be: 12 * 1/12 = 1ft tall 36 * 1/12 = 3ft long 8 * 1/12 = 8inches wide. Hope that helps

How is it a square if its 3ft by 1ft? The perimeter would be 7ft.

It is: 5*3 = 15 square feet

Area of rectangle = 38ft x 20ft = 760ft2 1sq yd = 1yd x 1yd = 3ft x 3ft = 9ft2 760ft2 / 9 ~= 84.4 sq yds.

16ft..A perimeter is the distance around a shape. So if this is a 3 by 5ft rectangle , considering it has four sides, you add them all up so:3+3+5+5= 16so the perimeter is 16ft
