Question

Square shape of area 144 wire "moulded" to for rectangle of 14cm length and breadth of rectangle

Answer 1

Answer:

area of square=144cm^2=a^2

  =>                a=12cm

length of wire=perimeter of square=4a

                                                          =4*12

                                                          =48cm

perimeter of square =perimeter of rectangle               (as it is moulded)

 =>                         48=2(l+b)                                           (l=14cm)

  =>                        24=14+b

 =>                           b=10cm
