Neha drew the small house on the square grid. She starts a bigger copy whose base is the orange line. To keep the same ratio of width to total height, how many squares tall must the big copy be (from the base to the top of the roof)?

Question

Accepted Answer

15. Small house: width 4 squares, height 4 + 2 = 6 squares, so 4 : 6 = 2 : 3 . Orange base = 10 = 2 × 5 , so height = 3 × 5 = 15 . (12 adds 6 to both instead of multiplying.)
