PSLE Nicole had a rectangular piece of paper, 66 cm by 31.3 cm. She cut out as many squares as possible from the paper. The side of each square was 6 cm.
- How many squares did Nicole cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 31.3 ÷ 6
= 5 r 1.3
Number of squares that can be cut out lengthwise
= 66 ÷ 6
= 11 r 0
Total number of squares
= 11 x 5
= 55
(b)
Remaining breadth of the paper left = 1.3 cm
Area of the paper left
= 66 x 1.3
= 85.8 cm
2 Answer(s): (a) 55; (b) 85.8 cm
