PSLE Roshel had a rectangular piece of paper, 69 cm by 33.7 cm. She cut out as many squares as possible from the paper. The side of each square was 3 cm.
- How many squares did Roshel cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 33.7 ÷ 3
= 11 r 0.7
Number of squares that can be cut out lengthwise
= 69 ÷ 3
= 23 r 0
Total number of squares
= 23 x 11
= 253
(b)
Remaining breadth of the paper left = 0.7 cm
Area of the paper left
= 69 x 0.7
= 48.3 cm
2 Answer(s): (a) 253; (b) 48.3 cm
