Answer 1

Answer:

OPTION:-D

STEP BY STEP EXPLANATION

$5 \times 12 = 13 \\ {5}^{2} + {12}^{2} = \sqrt{25 + 144} = \sqrt{169} = 13 \\ 8 \times 15 = 17 \\ {8}^{2} + {15}^{2} = \sqrt{64 + 225} = \sqrt{289} = 17 \\ similarly \: that \\ 7 \times 24 = 25 \\ {7}^{2} + {24}^{2} = \sqrt{49 + 576} = \sqrt{625} = 25$

hence the required number is 25

I HOPE IT WILL BE HELPFUL SO PLEASE MARK ME BRAINLIST
