PSLE Kylie had a rectangular piece of paper, 54 cm by 29.2 cm. She cut out as many squares as possible from the paper. The side of each square was 6 cm.
- How many squares did Kylie cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 29.2 ÷ 6
= 4 r 5.2
Number of squares that can be cut out lengthwise
= 54 ÷ 6
= 9 r 0
Total number of squares
= 9 x 4
= 36
(b)
Remaining breadth of the paper left = 5.2 cm
Area of the paper left
= 54 x 5.2
= 280.8 cm
2 Answer(s): (a) 36; (b) 280.8 cm
