PSLE Gillian had a rectangular piece of paper, 41.8 cm by 36 cm. She cut out as many squares as possible from the paper. The side of each square was 6 cm.
- How many squares did Gillian cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out lengthwise
= 41.8 ÷ 6
= 6 r 5.8
Number of squares that can be cut out breadthwise
= 36 ÷ 6
= 6 r 0
Total number of squares
= 6 x 6
= 36
(b)
Remaining length of the paper left = 5.8 cm
Area of the paper left
= 5.8 x 36
= 208.8 cm
2 Answer(s): (a) 36; (b) 208.8 cm
