Arectangular pool is 21 meters wide and 28 meters long. if you swim diagonally across the pool, how many meters would you be swimming?

To figure this out, you must use the Pythagorean theorem.
That is were you take the width of the opject, and square it (21 squared). and take the length of the object and square it (28 squared),
 then add those together. (21 squared + 28 squared) = NUMBER
then take that number that you got, and find the square root of it. (√NUMBER)
and that's your answer.

So it would be: 35 meters

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a

Answer:

$4034.40

step-by-step explanation:

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
