Answer 1

hope this helps u

answer =         = 139/3 = ⁴⁶ ¹/₂ cm square units

given

length  =  12 1/2 = 25/2 = 12.5

wide = 10  2/3 = 32/3

we will take the unit in fractions

perimeter of a rectangle =  2l+2b or 2(l+b)

                                            = 2* 25/2 +2*32/3 here in length 2 and 2 get cancelled

                                           =25+64/3 taking lcm

                                               = 75+64/ 3

                                              = 139/3 cm square is the answer

                                                 = 139/3 = ⁴⁶ ¹/₂ cm square units

we can convert it into decimal also mate
