PSLE Wendy had a rectangular piece of paper, 40.3 cm by 24 cm. She cut out as many squares as possible from the paper. The side of each square was 4 cm.
- How many squares did Wendy cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out lengthwise
= 40.3 ÷ 4
= 10 r 0.3
Number of squares that can be cut out breadthwise
= 24 ÷ 4
= 6 r 0
Total number of squares
= 6 x 10
= 60
(b)
Remaining length of the paper left = 0.3 cm
Area of the paper left
= 0.3 x 24
= 7.2 cm
2 Answer(s): (a) 60; (b) 7.2 cm
