so there are : a rectangle with length 12 m and width 2 m and a triangle with base length 12 m and height 5 m do you know formula of areas of this rectangle and triangle ?

OpenStudy (anonymous):

nope

jhonyy9 (jhonyy9):

area rectangle = length time width area triangle = base length time heigth divide 2

OpenStudy (anonymous):

ok

jhonyy9 (jhonyy9):

can you calculi them so now ?

OpenStudy (anonymous):

ill try

jhonyy9 (jhonyy9):

ok do you like i check it ?

the total area not is 30 ?

OpenStudy (anonymous):

ok

jhonyy9 (jhonyy9):

area of the triangle is = 12*5/2 = ?

OpenStudy (anonymous):

30

jhonyy9 (jhonyy9):

area of rectangle = 12*2 = ?

OpenStudy (anonymous):

60

jhonyy9 (jhonyy9):

yes 30 m^2 is area of triangle

jhonyy9 (jhonyy9):

what is this 60 ?

jhonyy9 (jhonyy9):

area of rectangle = 12*2 = ?

jhonyy9 (jhonyy9):

soi area of rectangle = 12*2 = 24 so are of this figure will be 30+24 = 54 m^2

jhonyy9 (jhonyy9):

do you understand it now ?

jhonyy9 (jhonyy9):
