<u>Figure - 1</u> :

Let the missing side as " n "

\mathrm{ \triangle DEF    \sim   \triangle DRQ}

Therefore the sides will be proportional,

  • \dfrac{n}{9}  =  \dfrac{4}{12}

  • n =  \dfrac{1}{3}  \times 9

  • n = 3 \:  \: units

_____________________________

<u>Figure - 2</u> :

Let the missing side as " m "

The Triangles are similar, therefore their sides will be proportional.

  • \dfrac{m}{8}  =  \dfrac{9}{6}

  • m =  \dfrac{3}{2}  \times 8

  • m = 3 \times 4

  • m = 12 \:  \: units

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}}}.

Darla spent $120.37 on groceries in January, $108.45 in February, and $114.86 in March. What was the average monthly cost of Dar
kari74 [83]
In order to find an average, you have to add all the numbers and divide by the number of things you added.

120.37 + 108.45 + 114.86 = 343.68
343.68/3 = 114.56

She spent an average of $114.56 each month on groceries.
