PSLE Roshel had a rectangular piece of paper, 44.2 cm by 25 cm. She cut out as many squares as possible from the paper. The side of each square was 5 cm.
- How many squares did Roshel cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out lengthwise
= 44.2 ÷ 5
= 8 r 4.2
Number of squares that can be cut out breadthwise
= 25 ÷ 5
= 5 r 0
Total number of squares
= 5 x 8
= 40
(b)
Remaining length of the paper left = 4.2 cm
Area of the paper left
= 4.2 x 25
= 105 cm
2 Answer(s): (a) 40; (b) 105 cm
