I just did the 2(trapezoid+triangles) area and got 24 but it is incorrect. anyone know why?

Can you show the steps you took?

#

Also you should only multiply one triangle and one trapezoid added together by 2

wary hornet Oct 8, 2024, 10:16 PM

#

yes i did that i can do it again

#

area of trapezoid = (1+4)/2 * 4 = 10

#

area of triangle = (1+4)/2 = 5/2
(10+5/2)*2 = 20+5 = 25

#

now i got 25 is this correct?

#

i don't think it is that simple, the answer should be a common fraction is what the question says.

#

The total area of both triangles is 1/4

wary hornet Oct 8, 2024, 10:24 PM

#

why isnt it 5?

winged cloud Oct 8, 2024, 10:24 PM

#

Why would it be

#

Base is 1, height is 1/4

wary hornet Oct 8, 2024, 10:24 PM

#

(1+4)/2 * 2 = 5

winged cloud Oct 8, 2024, 10:24 PM

#

BH/2=Area

#

I don’t know what you are doing

#

But it is 1 multiplied by 1/4

wary hornet Oct 8, 2024, 10:25 PM

#

give me a sec maybe im confusing the questions i'll circle what im looking at right now

#

#

winged cloud Oct 8, 2024, 10:27 PM

#

Yes

#

The red area is 1/4

wary hornet Oct 8, 2024, 10:29 PM

#

ok so you are saying that this part is 1/4?

winged cloud Oct 8, 2024, 10:29 PM

#

Between the blue lines

#

Yes

wary hornet Oct 8, 2024, 10:30 PM

#

#

but it says that the purple length is 4

winged cloud Oct 8, 2024, 10:30 PM

#

What?

#

The height at point 2 is 1

wary hornet Oct 8, 2024, 10:30 PM

#

it says the width is 4m wide tho

winged cloud Oct 8, 2024, 10:31 PM

#

Yes

#

From -2 to 2

#

Is 4

#

I said the height at point 2 is 1

wary hornet Oct 8, 2024, 10:31 PM

#

ohh i see, i was confused my bad.

#

isnt the width shortest side and length the longest?

winged cloud Oct 8, 2024, 10:31 PM

#

Not necessarily

#

Width is horizontal

#

Here

wary hornet Oct 8, 2024, 10:33 PM

#

i searched online and i think it is the shortest side no? i think it should say the length is 4. the wording is not very good then. thanks anyways tho

winged cloud Oct 8, 2024, 10:34 PM

#

wary hornet i searched online and i think it is the shortest side no? i think it should say ...

Width is defined as measurement from side to side

#

Horizontal width here is 4 because there are 4 total units in the span from -2 to 2

wary hornet Oct 8, 2024, 10:35 PM

#

so width always goes horizontally is that correct?

#

i was always taught that width is shortest side and length is the longest. pretty sure that is true. thanks anyways tho
