Answer: Hannah will pay $5,936.
Explanation:
Given: Length of pool = 30 feet
Width of pool = 15 feet
Area of pool = Length x Width = 30 feet x 15 feet
= 450 square feet
The patio will be 4 feet wide on each side of the pool.
i.e. Length of patio included pool = 30+4+4 = 38 feet
Width of patio included pool = 15+4+4 = 23 feet
Area of patio included pool = 38 feet x 23 feet
= 874 square feet
Area of patio = (Area of patio included pool ) - (Area of pool)
= (874 - 450) sq. feet
= 424 square feet
Rate = $14.00 per square foot
Cost for stone patio = Rate x Area of patio
= $ ( 14.00 x 424)
= $ 5,936
Hence, Hannah will pay $5,936.
