Answer:

Breadth = 10 cm.

Difference in area = 4 cm^2 ( the square encloses more area).

Step-by-step explanation:

The perimeter of the square = 4*12 = 48 cm.

If the length of the rectangle is 14 then

2*14 + 2b = 48 where b is the breadth.

28 + 2b = 48

2b = 20

b = 10 cm.

A square encloses more area than a rectangle for a given length of wire.

Area of the square = 12^2 = 144cm^2 and

area of the rectangle = 14*10 = 140 cm^2.

What is the area of the composite figure? ___ units^2

elena-14-01-66 [18.8K]

Answer:

34 square units

Step-by-step explanation:

The figure can be considered to be a trapezoid with a rectangle removed.

The area of the trapezoid is ...

A = (1/2)(b1 +b2)h

A = (1/2)(10 +6)(5) = 40

The area of the rectangle is ...

A = LW

A = (3)(2) = 6

Then the area of the shaded portion of the figure is ...

shaded area = trapezoid area - rectangle area

= 40 - 6 = 34 . . . square units

inysia [295]

Answer: 0.3413

Step-by-step explanation:

Given: an American household generates an average of 28 pounds of newspaper for garbage or recycling. Assume the standard deviation is 2 pounds.

Let $\mu=\text{ 28 pounds and }\sigma=\text{ 2 pounds}$ .

Let x be the random variable that denotes the amount of newspaper for garbage generated by each household each month.

If the data conforms to a normal distribution and a household is selected at random, the probability of its generating between 28 and 30 pounds per month is about

$P(28$

Hence, the required probability is 0.3413.
