PSLE Yen had a rectangular piece of paper, 60.2 cm by 28 cm. She cut out as many squares as possible from the paper. The side of each square was 4 cm.
- How many squares did Yen cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out lengthwise
= 60.2 ÷ 4
= 15 r 0.2
Number of squares that can be cut out breadthwise
= 28 ÷ 4
= 7 r 0
Total number of squares
= 7 x 15
= 105

Remaining length of the paper left = 0.2 cm
Area of the paper left
= 0.2 x 28
= 5.6 cm
