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?
