The diagonals of the rhombus are 4 and 8 cm. Find the side of the rhombus and its area.

We are given a rhombus with diagonals 4 and 8, so you can immediately find the area that will be equal to half the product of the diagonals, that is, (4 * 8) / 2 = 16. And its side will be from a triangle inside a rhombus, that is, according to T. Pythagoras: (16 + 2) this is under the root, and so our side is equal to the root of 20.
