Question

115 On a coordinate plane, draw triangle ABC with vertices
A(-1, -1), B(3, -1), and C(-1, 2). Find the area of the triangle
in square units.

Answer 1

Plotted the triangle... I’m presuming |-| is 1cm
So to find the area u plot the coordinates on a graph then work out the length then 1/2 the base the times the height which gives u 6cm^2
