Question

the length of diagnols of a rhombus are 24cm and 18 cm respectively, its area is​

Answer 1

Given :

• Length of diagonals of a rhombus :-
• First diagonal = 24 cm
• Second diagonal = 18 cm

To find :

• Area of rhombus

Knowledge required :-

• Formula of area of rhombus :-

⠀⠀⠀⠀Area of rhombus = ½ × d₁ × d₂

where,

• d₁ = First diagonal
• d₂ = Second diagonal

Solution :

Area of rhombus :-

⠀⠀⠀⇒ Area = ½ × 24 × 18

⠀⠀⠀⇒ Area = 12 × 18

⠀⠀⠀⇒ Area = 216

★ Area of rhombus = 216 cm²

Properties of rhombus :-

• All sides of rhombus are equal to each other.
• Diagonals of rhombus bisect each other at right angles.
• Opposite sides of rhombus are parallel to each other.
• The sum of two adjacent angles is equal to 180°.

Some related formulae :-

• Area of rhombus using base and height :-

→ Area = base of rhombus × height of rhombus

• Area of rectangle = length × breadth
• Area of square = side²
• Area of cube = side³
• Area of cuboid = 2(lb + bh +hl)
