A rectangular swimming pool is 19 meters wide by 35 meters long. What is the length of the diagonal of

the pool? Round to the nearest tenth.

The diagonal of the pool is 39.8 meters long.

Step-by-step explanation:

Since the pool has a rectangular shape it's diagonal forms a right triangle with the length and width of the pool, therefore we can use Pythagora's equation to calculate the length of the diagonal. This is shown below:

diagonal² = width² + length²

diagonal² = (19) ² + (35) ²

diagonal = sqrt (361 + 1225)

diagonal = sqrt (1586)

diagonal = 39.8 meters

The diagonal of the pool is 39.8 meters long.
