The area of a rhombus is 139.2cm.cm.and its altitude is 9.6cm.find the perimeter of the rhombus?

we know that

perimeter of rhombus=area / altitude
=139.2/9.6
=14.5
perimeter = 4a
=4(14.5)
=58cm

the base is 139.2/9.6 = 14.5

since all sides are the same, the perimeter is 4*14.5 = 58

To find the perimeter of the rhombus, we need to use the formula: Perimeter = 4 * side length.

First, let's find the side length of the rhombus using the given area and altitude.

The area of a rhombus is given by the formula: Area = base x altitude.

In this case, the base is equal to the side length of the rhombus.

139.2 cm² = base * 9.6 cm

Dividing both sides by 9.6 cm gives us the base (side length):

base = 139.2 cm² / 9.6 cm
base ≈ 14.5 cm

Now that we have the side length, we can calculate the perimeter using the formula:

Perimeter = 4 * side length

Perimeter = 4 * 14.5 cm
Perimeter = 58 cm

Therefore, the perimeter of the rhombus is 58 cm.

To find the perimeter of a rhombus, you need to know the length of one of its sides. In this case, we are given the area and the altitude of the rhombus, but not the length of its sides.

To find the length of one side of a rhombus using the given data, you can use the formula for the area of a rhombus:

Area = (d1 * d2) / 2

Where d1 and d2 are the lengths of the diagonals of the rhombus.

Since we are given the area, we can rearrange the formula to solve for one of the diagonal lengths:

d1 * d2 = Area * 2

Now, let's plug in the given values:

d1 * d2 = 139.2 * 2
d1 * d2 = 278.4

Unfortunately, we still don't have enough information to calculate the length of one side. The altitude does not directly give us a clue about the length of the diagonals. Therefore, we need more information to find the perimeter of the rhombus.
