1️⃣ 80 चौसेमी
2️⃣ 128 चौसेमी
3️⃣ 48 चौसेमी
4️⃣ 96 चौसेमी​

Answer 1

Given :-

• Side of rhombus = 10 cm.
• Diagonal of rhombus = 16 cm.

To Find :-

• Area of rhombus = ?

Answer :-

As we know that,

• Diagonals of a rhombus bisect each other at 90° .

Let us assume that , diagonal of other diagonal is 2x cm .

So,

→ (D1/2)² + (D2/2)² = (side)²

→ (2x/2)² + (16/2)² = 10²

→ x² + 8² = 100

→ x = √(100 - 64)

→ x = 6 cm .

then,

→ Diagonal of other diagonal = 2x = 2 * 6 = 12 cm.

therefore,

→ Area of rhombus = (1/2) * D1 * D2 = (1/2) * 16 * 12 = 96 cm². (Ans.)
