PSLE Emily had a rectangular piece of paper, 47.3 cm by 28 cm. She cut out as many squares as possible from the paper. The side of each square was 2 cm.
- How many squares did Emily cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out lengthwise
= 47.3 ÷ 2
= 23 r 1.3
Number of squares that can be cut out breadthwise
= 28 ÷ 2
= 14 r 0
Total number of squares
= 14 x 23
= 322
(b)
Remaining length of the paper left = 1.3 cm
Area of the paper left
= 1.3 x 28
= 36.4 cm
2 Answer(s): (a) 322; (b) 36.4 cm
