A quadratic equation with roots -1\(\frac{1}{2}\) and \(\frac{1}{4}\) is
x2 + 3x + 4 = 0
8x2 + 10x + 3 = 0
8x2 +12x – 3 = 0
8x2 + 10x-3.= 0
8x2 + 12x + 3 = 0

12cm
27cm
Correct answer is D
Area of a square = L X L = 81
: L = 9
Perimeter of square = 4 X L
4 X 9 = 36cm
An equilateral triangle with equal sides:
36/3 = 12cm
440cm\(^2\)
220cm\(^2\)
88cm\(^2\)
44cm\(^2\)
22cm\(^2\)
Correct answer is D
T.S.A of a cylinder = \(2\pi r (r + h)\)
= \(2 \times \frac{22}{7} \times 2 (2 + 1.5)\)
= 44 cm\(^2\)
