Ian drew a triangle ABX in a square grid as shown below.

1. (a)

   ABCD is a rectangle with the same area as triangle ABX. Draw ABCD on the grid above such that ABCD does not overlap with ABX.

2. (b)

   ABR is a right-angled triangle. The area of triangle BXR is the same as the area of triangle ABX. Draw ABR on the grid above such that ABR does not overlap with ABCD.

3. (c)

   Ian then drew another triangle Y in a square grid as shown below. Draw a parallelogram with the same perimeter as Y. Label the parallelogram P.
