PSLE Nora had a rectangular piece of paper, 41.3 cm by 34 cm. She cut out as many squares as possible from the paper. The side of each square was 2 cm.
- How many squares did Nora cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out lengthwise
= 41.3 ÷ 2
= 20 r 1.3
Number of squares that can be cut out breadthwise
= 34 ÷ 2
= 17 r 0
Total number of squares
= 17 x 20
= 340
(b)
Remaining length of the paper left = 1.3 cm
Area of the paper left
= 1.3 x 34
= 44.2 cm
2 Answer(s): (a) 340; (b) 44.2 cm
