Question

The diagonals of a rhombus are 5 cm and 7
cm. Its area will be . ... cm.​

Answer 1

Its area will be 17.5 square cm

Step-by-step explanation:

Let diagonals of rhombus

$d_1=5 cm, d_2=7 cm$

We know that

Area of rhombus=$\frac{1}{2}\times d_1\times d_2$

Where $d_1,d_2$ are diagonals of rhombus

Using the formula

Area of rhombus=$\frac{1}{2}\times 5\times 7 cm^2$

Area of rhombus=$\frac{35}{2} cm^2$

Area of rhombus=17.5 square cm

Hence, its area will be 17.5 square cm

Answer 2

The area of a rhombus is equal to 17.5 $cm^{2}$.

Step-by-step explanation:

Given,

The first diagonal of a rhombus($d_{1}$) = 5 cm and

The second diagonal of a rhombus($d_{2}$) = 7 cm

To find, the area of a rhombus = ?

We know that,

The area of a rhombus = $\dfrac{1}{2} \times$ Product of diagonals

= $\dfrac{1}{2} \times 5 cm \times 7 cm$

=  $\dfrac{35}{2} cm^{2}$

= 17.5 $cm^{2}$

∴ The area of a rhombus = 17.5 $cm^{2}$

Thus, the area of a rhombus is equal to 17.5 $cm^{2}$.
