PSLE Marion had a rectangular piece of paper, 66.6 cm by 33 cm. She cut out as many squares as possible from the paper. The side of each square was 3 cm.
- How many squares did Marion cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out lengthwise
= 66.6 ÷ 3
= 22 r 0.59999999999999
Number of squares that can be cut out breadthwise
= 33 ÷ 3
= 11 r 0
Total number of squares
= 11 x 22
= 242
(b)
Remaining length of the paper left = 0.59999999999999 cm
Area of the paper left
= 0.59999999999999 x 33
= 19.8 cm
2 Answer(s): (a) 242; (b) 19.8 cm
