Question

find area of a rhombus whose one side is 8 cm and height is0.8dm​

Answer 1

It is given that one of the side of the rhombus is 8 cm and the height is 0.8dm, and we have to find the area of a rhombus.

Now, we know that 1 decimeter=10 cm, then 0.8dm=0.8×10=8cm

Also, the area of the rhombus is given as:

A=b×h

A=8×8

A=64 sq cm

Thus, the area of the rhombus isA=64 sq cm

Answer 2

Answer:

64cm²

Step-by-step explanation:

Given:

>> One side is = 8cm

>> Height is = 0.8dm

To Find:

>> Area of Rhombus = ?

Formula used:

Area of Rhombus = breadth × height.

Procedure:

>> Convert deci - metre to cm.

$\bf {\boxed{\bf 1dm = 10cm}}$

So, 0.8dm will be 10 × 0.8

=> 8cm

>> We know area of Rhombus is breadth × height.

So,

$\implies \sf Area = 8cm \times 8cm$

$\implies \sf 64cm^2$

More approaches to find areas of different figures:-

$\sf \dfrac{1}{2} base \times height \implies Area \ of \ triangle$

$\sf length \times breadth \implies Rectangle's \ Area$
