Please answer this ​

Answer 1

Answer:

b) Rectangular board will require more length of golden strip

Step-by-step explanation:

Frame will be on the perimeter of the carboards.

perimeter of square cardboard = side x 4= 20cm x 4 = 80cm

perimeter of rectangular cardboard= 2(length + breadth)

                                                           = 2(40cm + 20cm)

                                                           = 2(80cm)

                                                          = 160 cm

∴ perimeter of rectangle = 160 cm

  perimeter of square = 80cm

  160cm > 80cm
