OpenStudy (habbster):

1/2[(18)(6)](15.59) - (21)(18)

OpenStudy (anonymous):

OpenStudy (anonymous):

@jim_thompson5910

OpenStudy (habbster):

yup

OpenStudy (anonymous):

I got 1,683.72 then - 378 and got 1,205.72

jimthompson5910 (jim_thompson5910):

you first need to cut 1,683.72 in half

OpenStudy (habbster):

you forgot to divide it by 2

jimthompson5910 (jim_thompson5910):

then you can subtract off 378

OpenStudy (habbster):

then subtract

jimthompson5910 (jim_thompson5910):

the basic idea is to find the area of the hexagon then find the area of the square then you subtract the two Shaded Area = (Area of Hexagon) - (Area of Square)

OpenStudy (anonymous):

how do I cut it in half?

OpenStudy (anonymous):

Do I square root it or divide it by 2? :)

jimthompson5910 (jim_thompson5910):

divide by 2

OpenStudy (habbster):

divide by 2

OpenStudy (anonymous):

okay so I cut it and got 84,186 and then I subtracted it by 378?

OpenStudy (habbster):

841.86*

OpenStudy (habbster):

then subtract

OpenStudy (anonymous):

463.86!

OpenStudy (habbster):

yup

OpenStudy (anonymous):

that's the area? :)

OpenStudy (habbster):

OpenStudy (anonymous):

Thank u so much! :)
