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?

Level 3
Roger had two planks of the same length. He sawed one plank into equal parts of length 90 cm. In each part he drilled 6 small holes as shown in Figure 1. After that, he sawed the other plank into equal parts of length 1.5 m and in each part, he drilled 8 big holes as shown in Figure 2. When he finished drilling, he counted that there were 12 more small holes than big holes. If all the holes are spaced equally, how many holes were there altogether?
