Question

the vertices of a right-angled triangle are A(1,0), B(7,0)and C(1,8).plot the points A, B and C on a sheet of graph paper hence find the area of ABC​

Answer 1

Answer:

area = 1/2 x base x height

base =6 height = 8

area = 1/2 x 6x8= 24 unitsquare

Step-by-step explanation:

point A ( 1,0) and point B (7,0). they both lie on the X axis.

point C (1,8), lies 8 units above point A parallel to the Y axis.

side AB = 7-1 = 6 units = base

side AC = 8-0 = 8 units = height

area = 1/2 x base x height

= 1/2 x 6 x 8 = 24 unit square
