86.
Fatima has 40
Nora has “6 + (40 x 2)”
6+(80) = 86
The total area of pool and border = 361 square feet.
Length of square pool = x
Length of square pool plus border = (x + 1 +1 ) = x + 2
There is 1 foot length on each side on the x length.
The other length of the square pool and border = (x + 2)
Area = (x+2)(x+2)
(x + 2)(x +2) = 361. Let A = x +2
A*A = 361
A² = 361 Take square root of both sides
A = √361
A = 19
A = x + 2 = 19
x = 19 - 2
x = 17
Area of square pool = x*x = 17*17 = 289
Area of the pool = 289 square feet.
Answer:
$157.45
Step-by-step explanation:
All the amounts provided in the question are supposed to be added as a fee, so if you add all the numbers you would get $157.45.
The perimeter of a square is the sum of all its sides' lengths
That means: perimeter =4*(7m+1)/3
Answer:
A=1/2(b*h)
A=(3x2*4xy)
A=1/2(12x3y)
A=6x3y
so the answer is option (d)
