Answer 1

Answer:

It might not be right

it is 18

Answer 2

Answer :-

Given :-

• A rhombus ABCD has diagonals of length 8 cm and 10 cm respectively.

Have to Find :-

• Find the area of the rhombus?

Solution :-

As we all know the area of Rhombus

Using Diagonal = ½ × Diagonal 1 × Diagonal 2

Substituting the values in the above formula :-

½ × 8 × 10

↬ 4 × 10

↬ 40 cm ²

Formulas to Calculate Area of Rhombus

• Using Diagonals $A$ = ½ × d1 × d2

• Using Base and Height A = b × h

• Using Trigonometry A = b² × Sin(a)

Other Important Formulas :-

↬ Perimeter of Rectangle = 2( L + B )

↬ Perimeter of square = 4 × Side

↬ Perimeter of triangle = AB + BC + CA

↬ Area of Rectangle = L × B

↬ Area of Square = ( side ) ²

↬ Area of Rhombus = Product of Diagonal/2.

↬ Area of Parallelogram = Base × Height.

↬ Area of triangle = 1/2 × base × height .
