PSLE Kathy had a rectangular piece of paper, 62 cm by 38.2 cm. She cut out as many squares as possible from the paper. The side of each square was 2 cm.
- How many squares did Kathy cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 38.2 ÷ 2
= 19 r 0.2
Number of squares that can be cut out lengthwise
= 62 ÷ 2
= 31 r 0
Total number of squares
= 31 x 19
= 589
(b)
Remaining breadth of the paper left = 0.2 cm
Area of the paper left
= 62 x 0.2
= 12.4 cm
