Answer 1

$A= \left[\begin{array}{cccc}a_{11}&a_{12}\\a_{21}&a_{22}\\a_{31}&a_{32}\\a_{41}&a_{42}{\end{array}\right] \\ \\ A= \left[\begin{array}{cccc}{3.1+2.1}&{3.1+2.2}\\{3.2+2.1}&{3.2+3.2}\\{3.3+2.1}&{3.3+2.2}\\{3.4+2.1}&{3.4+2.2}{\end{array}\right] \\ \\ A= \left[\begin{array}{cccc}{5}&{7}\\{8}&{12}\\{11}&{13}\\{14}&{16}{\end{array}\right]$
