Question

36. The three vertices of A ABC are A(1,4), B(-2,2) and C(3,2). Plot these
points on a graph paper and calculate the area of A ABC.

37. The three vertices of a rectangle ABCD are A(2,2), B(-3,2) and C(-3,5).
Plot these points on a graph paper and find the coordinates of D. Also,
find the area of rectangle ABCD.

38. The three vertices of a square ABCD are A(3,2), B(-2,2) and D(3,-3).
Plot these points on a graph paper and hence, find the coordinates of C.
Also, find the area of square ABCD.​
