Two carpets made of square tiles, each 36 tiles long, are pushed together as shown. One has 7 rows and the other has 3 rows. Using 36 × 7 + 36 × 3 = 36 × (7 + 3), how many tiles are there in all?

Question

Accepted Answer

360. Together the carpets make 36 tiles long and 7 + 3 = 10 rows: 36 × 7 + 36 × 3 = 36 × 10 = 360 — the distributive property. (252 counts only the blue carpet; 756 multiplies 36 × 7 × 3; 46 adds the labels.)

Two carpets made of square tiles, each 36 tiles long, are pushed together as shown. One has 7 rows and the other has 3 rows. Using $36 \times 7 + 36 \times 3 = 36 \times (7 + 3)$ , how many tiles are there in all?
