Let's assume these are the vertices in order and calculated the squared lengths of the sides. Let's calculate the vector for each side, which is the difference of the endpoints:

(7,10) - (4,7) = (3, 3)

(4,7) - (6,5) =(-2, 2)

(6,5) - (9,8) = (-3, -3)

(9,8) - (7,10) = (2, -2)

We see the pattern: (3,3) = -(-3,-3) and (-2,2) = -(2,-2)

We have two pairs of opposite vectors so we have a parallelogram.

Let's check the dot product of adjacent sides:

(3,3) . (-2, 2) = 3(-2) + 3(2) = 0

Zero dot product, we have perpendicularity. A parallelogram with one right angle is a

Answer: Rectangle

The adjacent sides are clearly not congruent so it's not a square

On a map the perimeter of the is 0.251 meters. The actual perimeters of the park is 1,000 times as large. What is the actual per

raketka [301]

The actual perimeter of the park is $\boxed{\bf251{\text{ meters}}}$ .

Further explanation:

Given:

The perimeter of the park is on a map $0.251{\text{ meters}}$ . The measured perimeter of the park is 1000 times as large.

Calculation:

The distance of the closed figure is called as the perimeter.

The perimeter of the attached Figure 1 can be calculated as,

$\begin{aligned}{\text{Perimeter}}&=a+a+b+b\\&=2\left({a+b}\right)\\\end{aligned}$

Here, $x,y{\text{ and }}z$ is the length of the shape.

From place value chart, 10 tens is equal to 1 hundreds.

Tenths are one place after the decimal and hundredths are two places after the decimal.

Two tenths can be written in the form of decimal as follows:

$\dfrac{2}{{10}}=0.2$

Five hundredths can be written in the form of decimal as follows:

$\dfrac{5}{{100}}=0.05$

One thousandths can be written in the form of decimal as follows:

$\dfrac{1}{{1000}}=0.001$

Therefore, the number 0.251 can be written as,

$\begin{aligned}0.251&=\frac{2}{{10}}+\frac{5}{{100}}+\frac{1}{{1000}}\\&=0.2+0.05+0.001\\&=0.251\\\end{aligned}$

On the map the perimeter of the park is $0.251{\text{ meters}}$ .

Let ${\text{P}}$ be the actual perimeter of the park.

The actual perimeter of the park can be calculated as follows,

$\begin{aligned}{\text{P}}&=0.251\times1000\\&=251{\text{ meters}}\\\end{aligned}$

Thus, the actual perimeter of the park is $\boxed{\bf251{\text{ meters}}}$ .

How many feet are in 100meters

77julia77 [94]

Answer: 328 feet, 1 inch

Step-by-step explanation:

3.281 feet makes 1 meter

To solve the question, Multiply the value by 3.281:

100 meters = 100 x 3.281 feets

=328.1 feet
