Solve:-
1. If length of a diagonal of a rhombus is 30 cm and it's area is 240 sq.cm. Find it's perimeter.

Answer:

1. Given that ;

Length of the Diagonal Rhombus ( d1 ) = 30cm

Area of the Rhombus ( A ) = 240cm²

Formula :

Area of the Rhombus ( A ) = 1 / 2 × d1 × d2

A = 240cm²

240 = 1 / 2 × 30 × d2

480 = 30 × d2

d2 = 480 / 30

d2 = 16cm

Perimeter of the Rhombus ( P ) = ?

Formula :

Perimeter of the Rhombus ( P ) = 4a

4 ( 30 )

120cm
