PSLE Betty had a rectangular piece of paper, 44.7 cm by 30 cm. She cut out as many squares as possible from the paper. The side of each square was 6 cm.
- How many squares did Betty cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out lengthwise
= 44.7 ÷ 6
= 7 r 2.7
Number of squares that can be cut out breadthwise
= 30 ÷ 6
= 5 r 0
Total number of squares
= 5 x 7
= 35
(b)
Remaining length of the paper left = 2.7 cm
Area of the paper left
= 2.7 x 30
= 81 cm
2 Answer(s): (a) 35; (b) 81 cm
