six digits in the triangle>Let T =6 eight digits in the rectangle>Let R=8 Total = 10 digits. = T union R (in other words, T OR R) get this much ?

how do u get 10 digits?

hartnn Group TitleBest ResponseYou've already chosen the best response.1
0 to 9 means total 10 digits i assumed that the digits are not repeated, which is a fair assumption here...

ohk...no they not repeated

digits are in the part that belongs to "both" figures = T AND R (T intersection R) = ...... there is a formula for this, you know ? in terms of T,R and T UNION R

now look at that figure, if u want total area of composite figure, will it be appropiate to add the area of triangle and rectangle ?

by the area of composite figure do u mean the overlapped shape?
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
yes,. because then you will consider the "intersection part" twice. once in rectangle and once in triangle, got this ?

um..kinda

hartnn Group TitleBest ResponseYou've already chosen the best response.1
so to get area of composite figure, u need to subtract are of intersection, right ?

..uh..yea..

hartnn Group TitleBest ResponseYou've already chosen the best response.1
so , we get TOTAL = RECT +TRIANGLE  INTERSECTION. in this case, total = 10 , Rect = 8, triangle =6 u just need intersection

hartnn Group TitleBest ResponseYou've already chosen the best response.1
so, 10 = 8+6x where x is digits that belongs to both figures

hartnn Group TitleBest ResponseYou've already chosen the best response.1
yes, so there are 4 numbers that belong to both..
