5. A rectangular swimming pool is 25 feet wide

and the diagonal measure is 47 ft. How long is the
swimming pool to the nearest tenth of a foot?
(Leave answer as a decimal. Round to the nearest tenth)
Help please?????

Answer 1

Explanation:

The width is 25ft

The diagonal is 47ft

The length can be calculated using pythagoras theorem

sqr Hypothenus= sqr opposite + sqr adjacent

47^2 = 25^2+ length^2

2209 = 625+ length^2

2209-625 = length^2

1584 = l^2

l = sqrt 1584 = 39.7994974843

Length = 39.8 ( nearest tenth)
