PSLE Cindy had a rectangular piece of paper, 66.1 cm by 36 cm. She cut out as many squares as possible from the paper. The side of each square was 4 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
= 66.1 ÷ 4
= 16 r 2.1
Number of squares that can be cut out breadthwise
= 36 ÷ 4
= 9 r 0
Total number of squares
= 9 x 16
= 144
(b)
Remaining length of the paper left = 2.1 cm
Area of the paper left
= 2.1 x 36
= 75.6 cm
2 Answer(s): (a) 144; (b) 75.6 cm
