Area Aptitude Test Paper 311) What is the area of a square field whose side is 20 meters?
Answer: C Explanation: The area of a square = (side) ^{2 } 12) What is the area of a square field whose diagonal is 40 meters?
Answer: B Explanation: Area of a square = 1/2 (diagonal) 2 = 1/2 (40)^{2} = 1/2 * 1600 = 800 sq. m. 13) The length of a rectangle is thrice its breath, and its perimeter is 106 meters. What is its area?
Answer: A Explanation: Let the breath = x So, the Length = 3x Perimeter of a rectangle = 2 (Length + Breadth) Now, Breadth = 13, so, length = 13 * 3 = 39 So, its area = Length * Breadth 14) A rectangular grass field has a length of 85 meters and breadth of 65 meters. It is surrounded by a 5meter wide path. Find the area of the Path and the cost of constructing it at Rs. 5 per square meter?
Answer: C Explanation: Area of the entire grass field including the path = Length (85 + 5 +5) * Breadth (65 + 5+5) Area of the grass field excluding the path = 85 * 65 = 5525 sq. m. So, area of the path = 7125  5525 = 1600 sq. m. The cost of constructing is Rs. 5 per square meter. So, the cost of constructing the entire path = 1600 * 5 = Rs. 8000 15) If the area of the trapezium, whose parallel sides are 6 cm and 10 cm is 32 sq. cm, what will be the distance between the parallel sides?
Answer: B Explanation: Parallel sides of a trapezium = 6 cm, and 10 cm 32=8 × distance Distance = 32/8 = 4 cm So, the distance between the parallel lines of trapezium = 4 cm.
