PSLE Jaslyn had a rectangular piece of paper, 48 cm by 27.4 cm. She cut out as many squares as possible from the paper. The side of each square was 6 cm.
- How many squares did Jaslyn cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 27.4 ÷ 6
= 4 r 3.4
Number of squares that can be cut out lengthwise
= 48 ÷ 6
= 8 r 0
Total number of squares
= 8 x 4
= 32
(b)
Remaining breadth of the paper left = 3.4 cm
Area of the paper left
= 48 x 3.4
= 163.2 cm
2 Answer(s): (a) 32; (b) 163.2 cm
