Question

A swimming pool is 20meters wide and has a diagonal length of 52meters. How much shorter is it than a 50meters pool?

Answer 1

Answer:

2m

Step-by-step explanation:

Length of swimming pool = √(52)²-(20)² = √(52+20)(52-20) = √72*32 = √2304 = 48m

shorter than 50m pool = 2m (Ans.)

Answer 2

Answer:

The given pool is 2m shorter than a 50m pool

Step-by-step explanation:

The given swimming pool is 20m wide and has a diagonal length of 52m. This represents a right-angled triangle. Let the length of the pool be L. Using Phythagoras theorem, we get:

52^2 = 20^2 + L^2

L^2 = 2704 - 400

      = 2304

L = √2304

L = 48m

The longer side of the pool is 48m, which is 2m shorter than a 50m pool.
