within 50 ft - 400 to 450 fps within 100 ft- 500 and up fps
at least 50 feet
133 ft
25 x 50 = 1250 sq ft
It is 50*30 = 1500 sq ft.
area of 50' by 20' is 50 ft x 20 ft = 1000 sq ft.
50*50 = 2500 square feet
50 ft * 135 ft = 0.155 acres, approx.
20 ft * 50 ft = 1000 ft2
50 ft is larger than 7 yards. 50 ft > 21 ft
1 ft = 0.3048 m or 1 m = 3.28084 ft thus 50 m = 50*3.28084 = 164.042 ft Direct Conversion Formula 50 m* 1 ft 0.3048 m = 164.0419948 ft
