maybe need help in all of them but for now need help on those one first

- anonymous

if I help you question, can you give me a medal?

- anonymous

yea

number 1 you want Perimetr an Area?

- anonymous

1) P = (3.8m*4) = 15.2m
\[A = 3.8m^{2}=14.44m ^{2}\]

- anonymous

2) P = 4.7+2.5+2.5+3.2= 12.9ft
A = frist extention picture like Rectangle
and do area Rectangle
A= (4.7ft)*(2.5ft)=11.75ft
than find area triangle
A triangle = (b*h)/2
base= 4.7ft - 2.5ft = 2.2ft
A triangle= (2.2*2.5)/2=2.75ft
A rec - A tri = 11.75ft - 2.75ft =9ft

number 3 , 9 is dimeter or radius?

- anonymous

if dimeter is 9 than
\[3) Per, cir = Dime* \pi\]
= 3.14* 9
P = 28.26
\[A = \pi * r^{2} = \pi3.14^{2} = 63.61\]

- anonymous

4) p = pi*dimeter
P = pi * 30ft = 94.25 ft
half cir than division by 2
94.25/2= 47.12ft
A = pi * r^2
A = pi * 15^2
= 706.86ft^2
half circle than division by 2

- anonymous

A=353.43ft^2

- anonymous

later use caculator check some time acident I hit wrong number

- anonymous

so what the area and perimeter for number 4

- anonymous

I did post A= 353.43ft^2
the rest let me write on the paper and I will post

- anonymous

you need 11 n 10?

- anonymous

no

- anonymous

let me work anothe number

- anonymous

ok

8 find the height , yes I find the heigh

- anonymous

9 find the base

- anonymous

look the question again

- anonymous

?

- anonymous

i need go rest room i be back

- anonymous

i think it 7.5 not 15 for number 9

- anonymous

number 9 Area is 97.5 and heigh is 13
find tha base (97.5*2)/13= 15

- anonymous

check :( 13*15)/2= 97.5 ?

- anonymous

ok it right

- anonymous

can you check my answer for number 5 and 6 i got for number 5 40 and for number 6 i got 21

- anonymous

5 and 6 take very long not easy ,pentagon has 5 side ie mean 5 triangle ,I have to find each side and 5 time triangle and use Trigonomertry to find base and heigh, do you have another question post you can come back , I will attach file When I'm done, 5 and 6 exactly the same only one 5 side one 6 side

- anonymous

what about number 11

- anonymous

I will do alll give me more time, if you have some thing to do come back ,I'm working now

- anonymous

##### 1 Attachment

6)
A=(3.5*3.03)/2= 10.6/2=5.3 cm^2
6 side have6 triangls than
(6*5.3) = 31.8 cm^2
Area hexagon is 31.8cm^2
good cluck with your home work

- anonymous

thank you so much

- anonymous

u r wel come , r u understand now?
