A floral design on a floor is made up of 16 tiles which are triangular, the sides of the triangle being 9 cm, 28 cm and 35 cm see figure. Find the cost of polishing the tiles at the rate of 50 paise per cm. A field is in the shape of a trapezium whose parallel sides are 25 m and 10 m.

The non-parallel sides are 14 m and 13 m. Find the area of the field. Semi-perimeter of the triangle, Ex RD Sharma Class 12 Solutions. Solution: The given class intervals are not continuous. Therefore, we first modify the distribution as continuous.

Now, the required frequency polygons are as shown below:. A random survey of the number of children of various age groups playing in a park was found as follows: Draw a histogram to represent the data above.

Solution: Here, the class sizes are different. So, we calculate the adjusted frequencies corresponding to each rectangle i. Therefore, we have the following table for length of rectangles. The required histogram is shown below: ii The maximum frequency is 44, which is corresponding to the class interval 6 � 8.

The following number of goals were scored by a team in a series of 10 matches 2, 3, 4, 5, 0, 1, 3, 3, 4, 3. Find the mean, median and mode of these scores. To find mode: In the given data, the observation 3 occurs 4 times, i. In a mathematics test given to 15 students, the following marks out of are recorded 41, 39, 48, 52, 46, 62, 54, 40, 96, 52, 98, 40, 42, 52, 60 Find the mean, median and mode of this data.

To find mode: In the given data, the observation 52 occurs 3 times, i. The following observations have been arranged in ascending order.

If the median of the data is 63, find the value of x. Find the mode of 14, 25,14, 28,18,17,18,14, 23, 22,14 and Solution: Arranging the given data in ascending order, we have 14, 14, 14, 14, 17, 18, 18, 18, 22, 23 25, Since the observation 14 is occuring the maximum number of times i.

Give one example of a situation in which i the mean is an appropriate measure of central tendency. Solution: i Mean height of the students of a class.

If the diagonals of a parallelogram are equal, then show that it is a rectangle. Show that if the diagonals of a quadrilateral bisect each other at right angles, then it is a rhombus.

Alternatively : ABCD can be proved first a parallelogram then proving one pair of adjacent sides equal will result in rhombus. Show that the diagonals of a square are equal and bisect each other at right angles. Show that if the diagonals of a quadrilateral are equal and bisect each other at right angles, then it is a square.

Thus, ABCD is a square. ABCD is a rhombus. Question 1. AC is a diagonal. Question 2.
