Question

Area of the trapezoid is 324, calculate the length of the longer base: (figure in comments)

Answer 1

just equate 2x+4=x+4 find x now then will tell you next step

Answer 2

x=0

Answer 3

or you can use area of trapezoid = 1/2* (sum of parallel sides)* 12

Answer 4

2x - 4 is the total length of base ???

Answer 5

324=0.5* (2x+4+x+4)*12 can you calculate x

Answer 6

oh okay

Answer 7

:)

Answer 8

Where are you seeing 2x + 4 @ghazi

Answer 9

the base length

Answer 10

Are you seeing it @oholmes

Answer 11

okay fine may be i made mistake while readin it.....it is so small
324=0.5(2x-4+x+4)*12

Answer 12

@oholmes can do this

Answer 13

yes sorry

Answer 14

what you got for x?

Answer 15

19.5?

Answer 16

nope x=18

Answer 17

648=3x*12=36x
and x=648/36=18

Answer 18

Its multiple choice question, 18 isnt one of the choices

Answer 19

now you have to put x= 18 in the longer side....

Answer 20

you have been asked to find length of longer side

Answer 21

32 isnt an answer either

Answer 22

well it should be 32

Answer 23

2*18-4=36-4=32

Answer 24

okay

Answer 25

clear?

Answer 26

I have the same figure but the area is now 234, would the answer be 22?

Answer 27

yes, clear

Answer 28

well 234=(1/2)*3x*12
234= 18x
x=13 so longer side = 2*13-4=22 ...yay!! you're right

Answer 29

thank you!
