Area Aptitude Test Paper 11) What is the area of a triangle with base 5 meters and height 10 meters?
Answer: C Explanation: Area of a triangle = ½ * base * height 2) The base of a rightangled triangle is 10 and hypotenuse is 20. What is its area?
Answer: D Explanation: The area of a right angled triangle = ½ * base * height Base = 10, Hypotenuse = 20 Area = ½ * base * height = ½ * 10 * 12= 60 meters 3) The sides of a triangle are in the ratio 10: 24:26 and its perimeter is 300 m. What is its area?
Answer: A Explanation: Let the sides are 10x, 24x, and 26x. So, the sides are 10 *5 = 50 meters The area of a right triangle is = 1/2 * base * height 4) The ratio of length and breadth of a rectangular park is 4:2. If a cat running along the boundary of the park at the speed of 18 km/hr completes one round in 10 minutes, find the area of the park in square meters.
Answer: A Explanation: One round of the park is equal to the perimeter of the park. So, by completing one round, the cat covers a distance equal to the perimeter of the park. Now, Distance or perimeter = speed * time Let Length = 4x and breadth = 2x So, Perimeter: 2 (4x + 2x) = 3000 So, Length = 4 * 250 = 1000 meters And, Breadth = 2 * 250 = 500 meters Area = Length * Breadth= 1000 * 500 = 50000 sq. m. 5) The perimeter of the rectangular field is 480 meters and the ratio between the length and breadth is 5:3. Find the area of the field.
Answer: C Explanation: Let the length of the rectangle be 5x, and breadth be 3x, ∴ Length = 5 x 30 = 150 m And, Area of rectangle = L x B Area Aptitude Test Paper 2 Area Aptitude Test Paper 3 Area Aptitude Test Paper 4 Area Aptitude Test Paper 5 Area Aptitude Test Paper 6 Area Aptitude Test Paper 7 Area Aptitude Test Paper 8
