Find area

[junior sage]

whats the area of this if it is a modified rectangle. isn't it the same as 12.1x5.16 using trapezoidal rule?

[waxen hawk]

depends how you modified it

[junior sage]

it was a rectangle

instead of straight lines

they are now a bit curvy

[waxen hawk]

it depends how they curve

clearly you can draw some different sized rectangles by drawing different curves

[junior sage]

ok

so it looked like this

originally

they then threw in a curve on the left hand side

and told us to find the estimation using trapezoidal rule

which now looks like this

and in theory

using the rule, it has the same area right

[gaunt kettle]

Not necessarily. Again, depends on the curve.

[junior sage]

its an estimation

but if the curve was the same size in both parts

its the same

right?

[pallid scaffold]

If the curve on one half gains x area and the second half loses x area then yes.

[junior sage]

ok

if that happens in the original image

shouldnt it be the same then?

[pallid scaffold]

This seems very vague. What are you trying to do exactly?

[junior sage]

find the area of the shape

i left the exact question at school

but thats the gist of it

i redrew it on some scummy site

[pallid scaffold]

Honestly more information is needed. But essentially the area of the shape changes by how much area is gained or lost by the variation. Without the actual question we can't do anymore than that. Also given this is high school level it's definitely not going to be looking at variational analysis. So, until you get that question I can't really help

ok thanks tho
