PSLE Yoko had a rectangular piece of paper, 43.4 cm by 27 cm. She cut out as many squares as possible from the paper. The side of each square was 3 cm.
- How many squares did Yoko cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out lengthwise
= 43.4 ÷ 3
= 14 r 1.4
Number of squares that can be cut out breadthwise
= 27 ÷ 3
= 9 r 0
Total number of squares
= 9 x 14
= 126
(b)
Remaining length of the paper left = 1.4 cm
Area of the paper left
= 1.4 x 27
= 37.8 cm
