PSLE Cathy had a rectangular piece of paper, 48 cm by 32.5 cm. She cut out as many squares as possible from the paper. The side of each square was 4 cm.
- How many squares did Cathy cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 32.5 ÷ 4
= 8 r 0.5
Number of squares that can be cut out lengthwise
= 48 ÷ 4
= 12 r 0
Total number of squares
= 12 x 8
= 96
(b)
Remaining breadth of the paper left = 0.5 cm
Area of the paper left
= 48 x 0.5
= 24 cm
2 Answer(s): (a) 96; (b) 24 cm
