Area and Perimeter Area and Perimeter 1 / 10 The area of a square is 1024 sq. cm. What is the respective ratio between the length and breadth of a rectangle whose length is twice the side of the square and breadth is 12 cm less than the side of the square? 5 : 18 16 : 5 14 : 5 32 : 5 2 / 10 The angles of a quadrilateral are in the ratio of 2 : 4 : 7 : 5. The smallest angle of the quadrilateral is equal to the smallest angle of a triangle. One of the angles of the triangle is twice the smallest angle of the triangle. What is the second largest angle of the triangle? 80° 60° 120° 90° 3 / 10 The length and breadth of a rectangle are increased by 20% and 5%, respectively. Find the percentage increase in its area. 10 15 25 20 4 / 10 The area of a circle and a square are equal, then the ratio of their perimeter is 1 : 1 2 : π π : 2 π : 4 5 / 10 The sides of a triangle are in a ratio of 5: 4 : 3. If its perimeter is 24 cm. what is the area of the triangle? 18 cm² 16 cm² 24 cm² 20 cm² 6 / 10 The areas of two concentric circles are 1386 cm2 and 1886.5 cm2 respectively. The difference between the radius of two circles is 7 cm 3.5 cm 2.75 cm 6 cm 7 / 10 What is the area of circle which radius is equal to the side of square whose perimeter is 140 m? 7700 14400 3850 1925 8 / 10 If the diameter of a circle is 28 cm then what will be its area? 308 616 1296 900 9 / 10 What will be the area of a square whose perimeter is 200 cm? 5000 10000 2500 1250 10 / 10 The area of the equilateral triangle, in which three coins of radius 1 cm are placed, as shown in the figure (6+4√3)sq cm (4√3-6)sq cm (7+4√3)sq cm 4√3 sq cm Your score isThe average score is 0% LinkedIn Facebook Twitter VKontakte 0% Restart quiz
