PSLE Vanessa had a rectangular piece of paper, 55.4 cm by 36 cm. She cut out as many squares as possible from the paper. The side of each square was 3 cm.
- How many squares did Vanessa cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out lengthwise
= 55.4 ÷ 3
= 18 r 1.4
Number of squares that can be cut out breadthwise
= 36 ÷ 3
= 12 r 0
Total number of squares
= 12 x 18
= 216
(b)
Remaining length of the paper left = 1.4 cm
Area of the paper left
= 1.4 x 36
= 50.4 cm
2 Answer(s): (a) 216; (b) 50.4 cm
