    Step-by-step explanation:

    6th to 10 classes formulas

    perimeter of a rectangle = 2 × (length + breadth)

    Perimeter of an equilateral triangle = 3 × length of a side

    Perimeter of a square = 4 × length of its side.

    (a +  {b)}^{2} =  {a}^{2} + 2ab +  {b}^{2}

    .

    (a +  {b)}^{2} =  {a}^{2} - 2ab +  {b}^{2}

     {a}^{2} +  {b}^{2} = (a +  {b)}^{2} - 2ab

    .

    .

     {a}^{2} -  {b}^{2} = (a + b) - (a - b)

    .

    more formulas there but which subject do you want you did said
