PSLE Cindy had a rectangular piece of paper, 56.2 cm by 38 cm. She cut out as many squares as possible from the paper. The side of each square was 2 cm.
- How many squares did Cindy cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out lengthwise
= 56.2 ÷ 2
= 28 r 0.2
Number of squares that can be cut out breadthwise
= 38 ÷ 2
= 19 r 0
Total number of squares
= 19 x 28
= 532
(b)
Remaining length of the paper left = 0.2 cm
Area of the paper left
= 0.2 x 38
= 7.6 cm
2 Answer(s): (a) 532; (b) 7.6 cm
