OpenStudy (freemap):

@jhonyy9

jhonyy9 (jhonyy9):

|dw:1456613184571:dw| and assume these areas and will get area of poligon

jhonyy9 (jhonyy9):

ok. ?

OpenStudy (freemap):

that doesn't help

jhonyy9 (jhonyy9):

why ? just see the graph and assume the necessary units first triangle has a base of 3 units and a height of 1 unit so what will be area of triangle ?

OpenStudy (freemap):

1.5 @jhonyy9

jhonyy9 (jhonyy9):

yes 3*1/2 = 1,5 unit squared - yes ?

jhonyy9 (jhonyy9):

in the same way try calculi area of second right triangle please

OpenStudy (freemap):

what are the points?

jhonyy9 (jhonyy9):

MOR

OpenStudy (freemap):

numbers?

jhonyy9 (jhonyy9):

for point O check my posted image please

OpenStudy (freemap):

3,3

jhonyy9 (jhonyy9):

but is the same like the base of the first right triangle - than you see it

jhonyy9 (jhonyy9):

not is right - sorry - how you have got it ?

OpenStudy (freemap):

e =0 in your post=3,3

jhonyy9 (jhonyy9):

|dw:1456613917592:dw|

OpenStudy (freemap):

7.5

jhonyy9 (jhonyy9):

exactly

jhonyy9 (jhonyy9):

so than area of rectangle = ?

OpenStudy (jdoe0001):

hmmm

OpenStudy (jdoe0001):

notice the picture, I think that's what jhonyy9 is mentioning

OpenStudy (freemap):

would it be 3, -3 for the points

jhonyy9 (jhonyy9):

thank you @jdoe0001 but i think than you see the graph the angle VMR not is right angle sure

OpenStudy (freemap):

okay, I'm lost now

jhonyy9 (jhonyy9):

try continue it from area of rectangle - ok. ?

OpenStudy (freemap):

what are the points?

jhonyy9 (jhonyy9):

please see the graph ? and numerate these units

jhonyy9 (jhonyy9):

length and width

jhonyy9 (jhonyy9):

from -3 to 3 are 6 units and on the top or bottom line how many units are there ?

OpenStudy (freemap):

5

jhonyy9 (jhonyy9):

on the left to axe y 2 units and on the right to axe y how many ?

jhonyy9 (jhonyy9):

yes 5 is the width of rectangle so area = ?

OpenStudy (freemap):

30

jhonyy9 (jhonyy9):

YES 6*5=30 units squared

jhonyy9 (jhonyy9):

total area = ?

OpenStudy (freemap):

30 is all I know

jhonyy9 (jhonyy9):

no 30 is area of the rectangle but there are again two right triangles so area of them you need assume to 30 and will get area of poligon - ok. ?

OpenStudy (freemap):

15

jhonyy9 (jhonyy9):

no just you need checking the above calculed 3 areas and assume them for area of poligon - right ?

jhonyy9 (jhonyy9):

the first was 1,5 second has ? rectangle has ? ----------------- area of poligon = ?
