A Walk Around The Swimming pool Alex wants to put a sidewal

A Walk Around The Swimming pool : Alex wants to put a sidewalk around his 16.0 foot by 36.0 foot rectangular swimming pool. A friend has concrete material left from another job that will cover an area of 450 square feet to the depth that Alex\'s sidewalk would require. If the sidewalk is of uniform width, what is the maximum width it can have?

Solution

Area of the swimming pool=lxb

=16x36=576 square feet

area of side walk=450 sq.feet

total area covered withside walk=area of side walk +area of the swimming pool

=450+576=1026 sq.feet
