Answer 2

Step-by-step explanation:

${1}^{2} = 1 \times 1 = 1$

$2 ^{2} = 2 \times 2 = 4$

${3}^{2} = 3 \times 3 = 9$

${4}^{2} = 4 \times 4 = 16$

${5}^{2} = 5 \times 5 = 25$

${6}^{2} = 6 \times 6 = 36$

${7}^{2} = 7 \times 7 = 49$

${8}^{2} = 8 \times 8 = 64$

${9}^{2} = 9 \times 9 = 81$

${10}^{2} = 10 \times 10 = 100$

${11}^{2} = 11 \times 11 = 121$

${12}^{2} = 12 \times 12 = 144$

${13}^{2} = 13 \times 13 = 169$

${14}^{2} = 14 \times 14 = 196$

${15}^{2} = 15 \times 15 = 225$

${16}^{2} = 16 \times 16 =2 56$

${17}^{2} = 17 \times 17 = 289$

${18}^{2} = 18 \times 18 = 324$

${19}^{2} = 19 \times 19 = 361$

${20}^{2} =20 \times 20 = 400$
