Question

if the perimeter of rhombus is 40 cm what will be its side​

Answer 1

$\Large{\underline{\underline{\bf{GivEn:-}}}}$

• Perimeter of rhombus = 40 cm

$\Large{\underline{\underline{\bf{To \: FiNd:-}}}}$

• What is the side of the rhombus ?

$\Large{\underline{\underline{\bf{SoLuTion:-}}}}$

Let the side of the rhombus be 'a' cm

To find the Perimeter of rhombus, we use the formula:-

$\large{\boxed{\bf{\star \: PERIMETER = 4 \times Side \: \star}}}$

According to question:-

➸ 40 = 4 $\times$ a

➸ $\sf{\cancel\dfrac{40}{4}}$ = a

❮ 10 cm = a ❯

❝ Hence, the side of a rhombus is 10 cm ❞

More To Know!

☆ Opposite sides are equal.

☆ Opposite angles are equal.

☆ Diagonals bisect each other.

☆ Diagonals are perpendicular.

☆ Diagonals bisect vertex angles.
