Question

A seating arrangement is made for the students to write an examination. Seats are arranged in rows and columns. The positions of three students are :student A is sitting at the 2nd row and the 7th column, student B is sitting at the 4th row and 11th column and student C is sitting at 6th row and 15th column i) find the position of each student as an ordered pair (x, y), if x represents the position of a student in a row and y represents the position of a student in column. ii) find the distance of a student B, from student A as well as student C. iii) another student D is sitting at the position represented by the point (8,13).find the area enclosed by student triangle And.

Answer 1

Step-by-step explanation:

I)

The coordinates of all three students can be written as

Student A = (2, 7)

Student B = (4, 11)

Student C = (6, 15)

ii)

Distance between A and B

= Sqr root {(4-2)^2 + (11-7)^2}

= 4.47

Distance between B and C

= Sqr root {(6-4)^2 + (15-11)^2}

= 4.47

III)

Information incomplete as which triangle is being referred ABC or D??
