PSLE Eva had a rectangular piece of paper, 56 cm by 29.7 cm. She cut out as many squares as possible from the paper. The side of each square was 4 cm.
- How many squares did Eva cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 29.7 ÷ 4
= 7 r 1.7
Number of squares that can be cut out lengthwise
= 56 ÷ 4
= 14 r 0
Total number of squares
= 14 x 7
= 98
(b)
Remaining breadth of the paper left = 1.7 cm
Area of the paper left
= 56 x 1.7
= 95.2 cm
2 Answer(s): (a) 98; (b) 95.2 cm
