area is scale factor squared in enlargement
area remains same in shear

 

[Spidey21]

area is scale factor squared in enlargement
area remains same in shear

oh han shear ka yaad hai but enlargement kaise multiply karenge??

 

[Spidey21]

area of object : area of image = 1 : (scale factor^2)
at least that is what i think the formula is. but u cud check by side ratio too!

tanx!!

20*6.9 x 10^7 = 138 x 10^7

china = 1.4 x 10^9 = 140 x 10^7
