PLS HELP MEEEEEEE ASAP

Answer 1

`{ \sf{a = { \blue{ \boxed{{53 \: \: \: \: \: \: \: \: }}}}} \: cm}`

Explanation:

`{ \mathfrak{formular}}\dashrightarrow{ \rm{4 * side \: length}}`

Each side has length of a?

`{ \tt{perimeter = a + a + a + a}} \\ \dashrightarrow{ \tt{ \: 212 = 4a}} \\ \\ \dashrightarrow{ \tt{4a = 212}} \: \\ \\ \dashrightarrow{ \tt{a = (212)/(4) }} \: \: \\ \\ { \tt{a = 53 \: cm}}`
