Question a is 48 i think! because if you do 12 x how many side there are. it’s 4 so 12 x 4

Answer:
242
Step-by-step explanation:
22=a/11
22*11= a
242 = a
a=242

I saw the image that should accompany the above problem.
Courtyard: Length=22 ft; Width = 12 ft
Fountain: Length = 6 ft; Width = ?
Area of the courtyard = 22 ft * 12 ft = 264 square feet
Part of the courtyard covered with stone has an area of 246 square feet.
Area of the fountain = 264 square feet - 246 feet = 18 square feet.
A) Width of the fountain.
Area of the fountain = Length * width
18 square feet = 6 ft * w
18 sq.ft / 6ft = w
3 ft = width
B.) Fraction of the area of the courtyard will be occupied by the fountain.
Area of the fountain: 18 square feet
Area of the courtyard: 264 square feet
18/264 = 3/44
18 ÷ 6 = 3
264 ÷ 6 = 44
Vertex form is
y = a(x - b)^2 + c
here a = -3 and b = -18 so we have
y = a(x + 3)^2 - 18
when x = 0 , y= 0 ( the y-intercept) so:-
0 = a(3^)2 - 18
9a = 18
a = 2
so the parabola is y = 2(x + 3)^2 - 18
x intercepts found as follows:-
2(x + 3)^2 - 18 = 0
(x + 3)^2 = 9
x + 3 = +/- sqrt9 = +/- 3
so x intercepts are 0 and -6 Answer
