PSLE Kylie had a rectangular piece of paper, 63.4 cm by 30 cm. She cut out as many squares as possible from the paper. The side of each square was 2 cm.
- How many squares did Kylie cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out lengthwise
= 63.4 ÷ 2
= 31 r 1.4
Number of squares that can be cut out breadthwise
= 30 ÷ 2
= 15 r 0
Total number of squares
= 15 x 31
= 465
(b)
Remaining length of the paper left = 1.4 cm
Area of the paper left
= 1.4 x 30
= 42 cm
