    B) Equilateral triangle = 12 cm; square = 9 cm

    C) Equilateral triangle = 15 cm; square = 10cm

    D) Equilateral triangle = 6 cm; square = 4 cm

    Correct Answer: B

    Solution :

    Perimeter of equil. \[\Delta =9\times 3=27\] Perimeter of square \[=12\times 4=48.\] (b) Perimeter of equil. \[\Delta =12\times 3=36\] Perimeter of square \[9\times 4=36.\] (c) Perimeter of equil. \[\Delta =15\times 3=45\] Perimeter of square = 40.
