Question

An 8.5 metre-wide pool is 4.5 times longer than it is wide.

If you were to swim diagonally across it six times, how far would you travel in total?

Give your answer to 2 decimal places.

Answer 1

Answer:

Total distance  = 253.74 m

Step-by-step explanation:

wide = 8.5 m

Length = 4.5 * 8.5 = 38.25 m

Pythagorean theorem:

(diagonal)² =  (38.25)² + ( 8.5)²

                    = 1463.0625 + 325.125

(diagonal)²   = 1788.1875

diagonal       = √1788.1875   = 42.29 m

distance traveled  = 6 * 42.29

                              = 253.74 m
