My scale factor is 3:7 or squared 9:49

$\frac{A_1}{A_2} = \frac{(L_1)^2}{(L_2)^2}$this is the formula i guess

4. Qwerty90

I suppose..

5. saifoo.khan

i forgot the formula. but give it a try. this must be it

6. Callisto

(9/21) ^2 = 113/x (3/7) ^2 = 113/x 9/49 = 113/x x= 615.2

@saifoo.khan the formula is correct
