A rectangular pool is 20 ft wide and 50 ft long. the deck is the same width all the way around the pool. the total area of the deck is 456 squared ft. how wide is the walkway

First, we need to get the total area of the rectangular pool.

Area = l * w

Area = 20 ft * 50 ft

Area = 1000 ft^2

Then the deck is 456 ft^2 with the width of 20ft, the same as the rectangular pool.

Area = l * w

456 = l * 20

l = 456 / 20

l = 22.8 ft.

So the walkway is 22.8ft wide.
