I get 90 square feet as follows. The perimeter is equal to twice the sum of the length and the width. P 2(L+W) so that the length plus the width is 19 ft. The combination of all pairs of integers that sum to 19 have products equal to or less than 9X10 90.
81 square feet.
for example you use a beam balance to find the mass of a rock sample for a science lab. you read the scale as 3.8g. what is your greatest possible error? well the rocks mass was measured to the nearest 0.1g, so the greatest possible error is one half of 0.1g he's right but here's the definition: one half of the unit of measurement to which the measure is being rounded. EX. the greatest possible answer of 3g is 1.5g If you have 3 cm, you are measuring to the nearest cm, so the greatest possibel error would be .5 cm.
first you must find the precision. that is the smallest possible unit of the smallest measurement. in this case the smallest measurement is 5/10ths. the smallest possible unit is 1/10. so 1/10 is the precision. to find the greatest possible error you have to multiply the precision (1/10) by 1/2. and you get 1/20. the greatest possible error is 1/20. another example: find the greatest possible error of both 6 and 3.214. for 6 the smallest unit would be 1 because you can go lower than one without going to the next unit down. so we then take one and multiply it by 1/2. one half is also 0.5. 1 multiplied by 1/2 is 1/2, therefore, the greatest possible error of 6 is 1/2 or 0.5. for the next number take the smallest unit of 214/1000, which is what .214 is. the smallest measurement would be 1/1000. that is our precision. the greatest possible error is one half (1/2) of the precision, or, 1/1000 x 1/2, which equals 1/2000. the greatest possible error of 3.214 is 1/2000. it's kind of confusing. i hope this helped. first it helps to understand the precision. then from there the gpe is half of the precision.
The smallest perimeter is 4*sqrt(24) = approx 19.6 cm There is no largest perimeter.
The answer depends entirely on how the dimensions change. It is possible to change the dimensions without changing the perimeter. It is also possible to change the dimensions without changing the area. (And it is possible to change the area without changing the perimeter.)
The greatest possible area is 90 square feet.
. What is the greatest area possible enclosed by a quadrilateral with a perimeter of 24 feet?
For any perimeter, the rectangle with the greatest area is a square.For a 16-inch perimeter, the greatest rectangular area is 16 square inches,inside a square with 4-inch sides.But if you don't necessarily need straight sides, then you can squeeze more areainside the same perimeter with a circle. A circle with a 16-inch circumference has anarea of 20.372 square inches.
It's greatest possible perimeter: 1+39+1+39 = 80 feet
Assuming that the measurement is to the nearest 0.01, the greatest possible error is 0.005.
0.5
For a given perimeter, its a square.
Max rectangular area for a given perimeter is a square.P = 100S = 25Area = 252 = 625 square feet
