Perimeter = 2( Length + Width)

Given that Perimeter = 3 1/12 feet and Width = 2/3 foot, plug the values into the formula to find the length:

3 1/12 = 2( Length + 2/3)

3 1/12 = 2Length + 4/3

2 Length = 3 1/12 - 4/3

2 Length = 7/4

Length = 7/4 ÷ 2

Length = 7/4 x 1/2

Length = 7/8

Now that we know the length is 7/8 and the width is 2/3, find the area:

Area = Length x Width

Area = (7/8)(2/3) = 7/12

Answer: Area = 7/12 ft²

Mariana [72]

Answer:

Step-by-step explanation:

$\frac{7}{13}$ -Female

$\frac{2}{3}$ - Men Married.

$\frac{7}{13} divided by \frac{2}{3} = \frac{7}{13} x\frac{3}{2} = \frac{21}{6} = 3\frac{2}{6} = 3\frac{1}{3}$

Lapatulllka [165]

Answer:

Step-by-step explanation:

There are 3 possibilities for the graph as shown in the figure.

(a) having zero intersection

(b) having one intersection point (touching point)

So, the greatest possible number of intersections for these graphs is 2 as shown in figure (c).

Based in the given figure, we are being asked to solve the area and the perimeter of the semicircle. As we evaluate the problem, we can get a radius measurement from the rectangle. Hence, the radius is half of 4 inches which is 2 inches and since we know the formula for solving the area of a circle which is Area = pi*r², dividing the result by two, we able to get the area of the half of a circle which is equivalent to the area of the semicircle.
Area of circle = pi*r²
Area of circle = 3.14*(2)² = 12.56
Therefore, area of semicircle is = (1/2) 12.56
Area of semicircle = 6.28 inches²

Solving for the perimeter:
Semicircle Perimeter = 1/2 * pi* d+d where d is the diameter (diameter = 4 inches)
Semicircle Perimeter = 1/2 * 3.14*4+4
Semicircle Perimeter = 10.28 inches
