Question

Diagonals of a Rhombus are 9 cm and 14 cm .Then its area equal to

(a) 63 2

(b) 126 2

(c) 81 2

(d) 56 2​

Answer 1

Given :- Diagonals of a Rhombus are 9 cm and 14 cm .Then its area equal to

(a) 63 cm²

(b) 126 cm²

(c) 81 cm²

(d) 56 cm²

Solution :-

we know that,

• Area of rhombus when diagonals D1 and D2 are given is = (1/2) * D1 * D2 .

we have,

• D1 = 9 cm.
• D2 = 14 cm .

so,

→ Area of rhombus = (1/2) * 9 * 14

→ Area of rhombus = 9 * 7

→ Area of rhombus = 63 cm² (a) (Ans.)
