Find the side of the rhombus whose diagonals are 20 cm and 48 cm.

1) A rhombus is a parallelogram that has equal sides. If a rhombus has all angles right, then it is called a square. Formula of the side of a rhombus through two diagonals: a = (√ (d1 ^ 2 + d2 ^ 2)) / 2.

2) According to the condition of the problem, the diagonals of the rhombus are 20 cm and 48 cm, that is, d1 = 20 cm, and d2 = 48 cm.

Substitute the known values into the formula to calculate the side of the rhombus through its diagonals specified in paragraph 1. We get: a = (√ (20 ^ 2 + 48 ^ 2)) / 2 = (√ (400 + 2304)) / 2 = ( √ (400 + 2304)) / 2 = (√2704) / 2 = 52/2 = 26 cm.
