ADRE 2024 • 2024 Paper 2Question 1
The length and breadth of a room are 8 meters and 6 meters respectively. Tom runs along all the four walls and finally along a diagonal in order to catch Jerry. How much total distance is covered by Tom?
A.38 meters ✓ (Correct)
B.10 meters
C.14 meters
D.28 meters
Explanation: Perimeter along four walls = $2(8 + 6) = 28$ meters. Length of diagonal = $\sqrt{8^2 + 6^2} = \sqrt{100} = 10$ meters. Total distance = $28 + 10 = 38$ meters[cite: 3].
ADRE 2024 • 2024 Paper 3Question 2
The base and the height of a right-angled triangle are equal in magnitude and the length of the third side is 2√2 cm. The area of the triangle is
A.2 sq. cm ✓ (Correct)
B.2√2 sq. cm
C.4 sq. cm
D.4√2 sq. cm
Explanation: Let base = height = $x$. Hypotenuse = $x\sqrt{2} = 2\sqrt{2} \implies x = 2$ cm. Area = $\frac{1}{2} \times 2 \times 2 = 2\text{ cm}^2$[cite: 5, 6].
