Question

who can tell me, all formulas in std 6 to 10 ​

Answer 1

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.

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

.

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

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

.

.

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

.
