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
F=(5,8) e=(4,3) d=(x,y)
(5+x)/2=4 (8+y)/2=3
5+x=8 8+y=6
x=3 y=-2
d=(3,-2)
Answer:
Ratio of the perimeters =3:1
Step-by-step explanation:
We have given that : Ratio of the sides of two squares is 3:1
To find : Ratio of their perimeters
Solution : Let the length of the sides are 3:1 = 3x : x
Formula of perimeter of square = 4(side)
Using the formula ,
Perimeter of 1 square = 4×3x= 12x
Perimeter of 2 square = 4×x= 4x
Ratio of the perimeter of 1 square and 2 square = 12x : 4x
= 3 : 1
