Question

Find the area of the triangle whose vertices are (0, 4), (0, 0) and (2, 0) by plotting them on the graph.

Answer 1

​

The triangle is a right-angled triangle with base 2 units and height 4 units.

Area of triangle = $\frac{1}{2}\times b\times h$
Area of triangle = $\frac{1}{2}\times 2\times 4$ = 4 sq. units.
