A football field is 160 feet wide. In College Football, the hash marks (inbounds markings, which designate the "pocket") are 40 feet apart, but they are wider for high school games and narrower for NFL.
20 feet wide (40 feet long)
(40 feet)(28 feet) = 1120 square feet.
12 x 40 = 480 square feet
200
240 square feet (40 x 6 = 240)
the answer is 960 square feet
40 yards across.
40 feet equates to 12.192 meters.
40
40 feet x 25 feet = 1,000 square feet.
Volume of greenhouse: 40*15*10 = 6000 cubic feet
1250 square feet is 25 feet wide by 50 feet long, or it could be 40 feet long by 31.25 feet wide.
