Answer 1

Answer:

answer is 80 for the following questions

Answer 2

Area of a rhombus is 24 .

Step-by-step explanation:

Given:

Let ABCD be the given rhombus with diagonals AC and BD which intersect each other at O such that AC = 8 cm.

Since diagonals of a rhombus bisect each other, we get

Let BO = x and AB = 5 cm   (given).

We know that diagonals of a rhombus cut each other at right angles. So ΔAOB is a right angled triangle.

Using Pythagoras theorem in ΔAOB, we get

x = 3 cm

Thus the length of another diagonal BD is,

BD = 2x = 6 cm.

Therefore the area of the rhombus is given by,

Area of rhombus =

Area(ABCD) =

                   =

                   =

Area of a rhombus is 24 .
