1 acre = 43,560 square feet
150 ft x 75 ft = (150 x 75 / 43,560) = 11,250/43,560 = 0.2583 acre (rounded)
0.4 hectare is almost exactly 1 acre. (.9884 acre) The conversion formula is 1 hectare = 2.47105381 acres. So actually, 0.4 ACRES = about 0.17 HECTARES - read the question fully, the right way round!
Yes, 510 rounded off to 3 significant figures would be 510.
Rounded value is 5.
You can't tell. There are an infinite number of different shapes that enclose 200 acres of area. Even if you only want to talk about rectangles, there are an infinite number of rectangles, with all different perimeters, that all enclose 200 acres. The smallest possible perimeter (distance around) is 10,463.2 feet / 1.98 miles if the 200 acre field is circular, or 11,806.4 feet / 2.236 miles if it's square. (All of these numbers are rounded off.) Any non-square field will have a perimeter greater than that. The less square it is, the longer the perimeter will be. For example, if the field is 1 foot wide and 1,650 miles long, then its area is 200 acres, and its perimeter is 3,300 miles and 2 feet.
The smallest whole number which, when rounded off to the nearest thousand, is equal to 8000 is 7500. This is because when you round 7500 to the nearest thousand, it becomes 8000.
OK, pi * r^2 = 3.14159*50^2, =7854yards sq. rounded off. 1.6227 acres

Use the following facts off the top of our head: 1 mile = 1.609344 kilometer, and 1 sq mile = 640 acres. Then: 1 mi2 = (1.609344)2 km2 = 2.59 km2 =640 acres and: 1 acre = 2.59/640 = 0.004047 km2 (rounded)
Infinitely many.
