Question

plot point A(-1,3) and B(4,0) on a graph paper. what figure you will get by joining these points to origin. find the area of the figure​

Answer 1

Given: The points A(-1,3) and B(4,0)

To find: The figure obtained by joining these points with origin.

Solution:

• Now we have given two points A(-1,3) and B(4,0) and origin.

• We can conclude that the figure formed will be triangle as there are three points.

• So, A(-1,3) and B(4,0) and C(0,0)

• Let the fourth point be D(-1,0).

               area of triangle ABC = area of triangle ABD - area of triangle ADC

               1/2 x (5) x (3) - 1/2 x (1) x (3)

               1/2 x (15 - 3)

               1/2 x 12

               12/2

               6 cm²

Answer:

                So the area of triangle formed will be 6 cm².
