PSLE Rachel had a rectangular piece of paper, 63 cm by 34.9 cm. She cut out as many squares as possible from the paper. The side of each square was 3 cm.
- How many squares did Rachel cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 34.9 ÷ 3
= 11 r 1.9
Number of squares that can be cut out lengthwise
= 63 ÷ 3
= 21 r 0
Total number of squares
= 21 x 11
= 231
(b)
Remaining breadth of the paper left = 1.9 cm
Area of the paper left
= 63 x 1.9
= 119.7 cm
2 Answer(s): (a) 231; (b) 119.7 cm
