Level 3 PSLE The figure is made up of two rectangles, ABHF and FGDE, and two right-angled isosceles triangles, BCH and DCG. BA = 13 cm, DE = 8 cm and BH = w cm. AFE and CHGF are straight lines.
Find the length of AE in terms of w. Give your answer in the simplest form.
Find the total area of the figure when w = 16.

Level 3 PSLE Jan used a total of 22 rods and straws to form a rectangular grid that was 2 rods long and 4 straws wide as shown in Figure 1.
Jan added more rods and straws to form a larger rectangular grid. The grid was 3 rods long and 5 straws wide. How many rods and straws were there in this grid?
Leon also used some rods and straws to form another rectangular grid. Part of his grid is as shown in Figure 2. What was the total number of rods and straws used?
