Answer:

perimeter = sum of all sides. this is same for polygons

rect: area l×b. peri = 2(l+b)

Step-by-step explanation:

Answer:

P = <u>40 cm</u>

Step-by-step explanation:

Here,

  • We can see that the given polygon is a rectangle.
  • The length and breadth of rectangle is 15 cm and 5 cm.

As we know that the formula of perimeter of rectangle is :

\longrightarrow{\pmb{\tt{P = 2(L +  B)}}}

  • P = Perimeter
  • L = Length
  • B = Breadth

Substituting all the given values in the formula to find the perimeter of rectangle :

\begin{gathered} \qquad{\longrightarrow{\sf{P = 2(L +  B)}}}\\\\\qquad{\longrightarrow{\sf{P = 2(15 +  5)}}}\\\\\qquad{\longrightarrow{\sf{P = 2(20)}}}\\\\\qquad{\longrightarrow{\sf{P = 2 \times 20}}}\\\\\qquad{\longrightarrow{\sf{P = 40}}}\\ \\ \qquad{\star{\underline{\boxed{\sf{ \red{P = 40 \: cm}}}}}}\end{gathered}

Hence, the perimeter of rectangle is 40 cm.

Find the value of x then tell whether the side lengths form a Pythagorean triple 6 , 10 , x
masya89 [10]

Answer:

Explanation:

Use the Pythagorean theorem (

a

2

+

b

2

=

c

2

)

Lets label the right triangle such that:

a

=

12

b

=

16

c

=

x

Thus,

12

2

+

16

2

=

x

=

x

400

=

x

2

√

400

=

x

20

=

x

So our missing side,

c

is

20

We can now say that the sides of our triangle are

12

,

16

,

20

I've included a link that lists a couple of Pythagorean triples (a couple because they are infinitely many).

After 8/15 of an hour, Jane has completed painting 3/5 of the wall. At this rate, how much of the wall will she finish painting
LuckyWell [14K]

Answer:

Step-by-step explanation:

Find the unit rate for this painting:

 3/5 of wall surface            3/5              15            9

------------------------------- = --------------- * --------- = -----------

         (8/15) hour                 8/15             15             8

Jane could actually paint the whole wall plus 1/8 more of it in one hour.

What is the value of x in the trangle? Enter your answer in the box. Round your final answer to the nearest hundredth.​
-Dominant- [34]

Use trigonometry.

cos(18°) = x/25

Multiply both sides by 25.

cos(18°)25 = x

23.7764129074 = x

We round off to the nearest hundredth. This means to round off to two decimal places.

Doing so, we get 23,78 cm = x.
