Answer:
40cm
Step-by-step explanation:
1. To find the missing leg, use the Pythagorean theorem a²+ b² = c² and substitute the numbers a² + 8² = 17².
2. So a = 15 since 17²-8² = 289 - 64 =225 and the square root of 225 is 15
3. Now that all the lengths have been found. So the perimeter of the right triangle is 40cm.

Time taken to fill the bathtub is 8 min
time taken to drain the bathtub is 12 min
fraction of bathtub filled in 1 hour=1/8
fraction of bathtub drained in 1 hour=1/12
fraction that will be filled in a minute given that both taps are opened at he same time:
1/8-1/12
=1/24
thus time taken for the bathtub to be filled is 24 min
