A floor design on a grid is a big 7-by-6 rectangle. Inside it, a 3-by-2 rectangle and a 2-by-2 square are left uncoloured. How many square units of the floor are coloured?

Accepted Answer

32. Big rectangle = 7 x 6 = 42. Uncoloured = (3 x 2) + (2 x 2) = 6 + 4 = 10. Coloured = 42 - 10 = 32 square units.
