I don't get it and I have tried it multiple ways

jasenka [17]

Answer:

9350 m²

Step-by-step explanation:

There are several ways you can go at this. Here are 3 of them:

along an extension of the lower right vertical edge, divide the figure into a rectangle and a right triangle.
between the upper left corner and the inside corner at lower right draw a diagonal line to divide the figure into a trapezoid and a triangle.
subtract the area of the trapezoid at the right from the area of the bounding rectangle

The relevant formulas for area are ...

rectangle: A = LW . . . . . . . . . . . length times width

trapezoid: A = (1/2)(b1 +b2)h . . . b1, b2 are the bases, h is the height

triangle: A = (1/2)bh . . . . . . . . . . . b is the base, h is the height

Here's what those computations look like:

1. rectangle: 60m wide by 80 m high = 4800 m².

right triangle: base 190-60 = 130 m; height = 80-10 = 70 m.

area = (1/2)(130 m)(70 m) = 4550 m²

figure area = 4800 m² +4550 m² = 9350 m² . . . . area of figure

2. The trapezoid has bases of 80 m and 10 m, and a height of 60 m. Its area is ...

A = (1/2)(80 m +10 m)(60 m) = 2700 m²

The triangle has a base of 190 m and a height of 80-10 = 70 m. Its area is ...

A = (1/2)(190 m)(70 m) = 6650 m²

Then the total area is 2700 m² +6650 m² = 9350 m² . . . total area

3. The bounding rectangle is 190 m by 80 m, so its area is ...

A = LW = (190 m)(80 m) = 15200 m²

The (negative) trapezoid at right has bases of 10 m and 80 m, and a width of 190-60 = 130 m. Its area is ...

A = (1/2)(10 m +80 m)(130 m) = 5850 m²

The area of the figure is the difference between these:

figure area = 15200 m² -5850 m² = 9350 m² . . . figure area

Find the area A of the polygon with the given vertices.

Natalija [7]

Answer:

A = 35 square units

Step-by-step explanation:

Formula to calculate the distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is,

d = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Length of the segment between A(2, 2) and B(9, 2) = $\sqrt{(9-2)^2+(2-2)^2}$

= 7 units

Length of the segment between B(9, 2) and C(9, -3) = $\sqrt{(9-9)^2+(2+3)^2}$

= 5 units

Length of the segment between C(9, -3) and D(2, -3) = $\sqrt{(9-2)^2+(-3+3)^2}$

= 7 units

Length of the segment between A(2, 2) and D(2, -3) = $\sqrt{(2-2)^2+(2+3)^2}$

= 5 units

Therefore, given polygon is a rectangle.

Area of the rectangle = length × width

= 7 × 5

= 35 square units

Which statement about the values 0.034 and 3.40 are true

Nana76 [90]

Answer:

See Explanation

Step-by-step explanation:

This question requires options.

Since none is provided, I will give a general solution.

We have: 0.034 and 3.40

Required

The relationship between them

3.40 can be expressed as:

$3.40 \to 0.034 * 100$

This means that 3.40 is 100 of 0.034

Similarly, 0.034 can be expressed as:

$0.034 \to 3.40 * \frac{1}{100}$

This means that 0.034 is 1/100 of 3.40

Question 1 (3 points)

Leokris [45]

Answer:

A) The slope of a line is basically the steepness of it or it can be defined as the change in y for a unit change in x along the line.

B) -1

Step-by-step explanation:

The point here are ( -2,6 ) and ( 0,4 ).

Here $x_1=-2$ , $y_1=6$

And $x_2= 0$ , $y_2=4$

$m=\frac{4-6}{0-(2)} =-1$
