Answer:
D
Step-by-step explanation:
28×14=392, which generally already gives you the answer. But the extra area is a trapezoid so we do 4+6=10×2(height)=20, but we have to divide by two since its a trapezoid giving us 10. So 10+392=402
271,403.00000
Step-by-step explanation:
----------------------------------------
Define x:
----------------------------------------
Let x be the length of the pool.
Length of the pool and its border = x + 1 + 1
Length of the pool and its border = x + 2
----------------------------------------
Given area = 361 ft², find x:
----------------------------------------
(x+2)² = 361
x+ 2 = √361
x + 2 = 19
x = 19 - 2
x = 17
----------------------------------------
Find Length of the pool:
----------------------------------------
Length of the pool = x = 17 feet
----------------------------------------
Find Area of the pool:
----------------------------------------
Area = 17 x 17
Area = 289 ft²
------------------------------------------------------------
Answer: Area of the pool = 289 ft²
------------------------------------------------------------
