PSLE Sarah had a rectangular piece of paper, 42 cm by 37.3 cm. She cut out as many squares as possible from the paper. The side of each square was 6 cm.
- How many squares did Sarah cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 37.3 ÷ 6
= 6 r 1.3
Number of squares that can be cut out lengthwise
= 42 ÷ 6
= 7 r 0
Total number of squares
= 7 x 6
= 42
(b)
Remaining breadth of the paper left = 1.3 cm
Area of the paper left
= 42 x 1.3
= 54.6 cm
2 Answer(s): (a) 42; (b) 54.6 cm
