SSC CPO 2020 PYQ — Question 105

The correct answer is Option 3 i.e. 120.

Given that,

a = 13 cm, d₁ = 13 cm, and d₂ = ?

⇒ d₂ $=2 \sqrt{13^2-12^2}$ 

⇒ d₂ = $2 \sqrt{169-144}$

⇒ d₂ = $2 \sqrt{25}$ = 2 × 5 = 10  

Area of the rhombus = $\frac{1}{2} \mathrm{~d}_1 \times \mathrm{d}_2$

⇒ $\frac{1}{2} \times24\times10$

⇒ 12 × 10 = 120 cm²

Area of the rhombus = 120 cm²
