(1+2)(3+1)=12

(2+3)(3+4)=35

similarly other 2 equations

55*55

(5+5)(5+5)=10*10=100

therefore the answer is 100.

Answer 2

Answer:

12×31=12 (1+2×3+1)

23×34=35(2+3×3+4)

34×51=42(3+4×5+1)

54×11=18(5+4×1+1)

So...,

55×55=??? {You have to use the same procedure which I have used at first}

5+5×5+5=10×10=100

SO THE ANSWER IS 100......
