PSLE Hilda had a rectangular piece of paper, 44 cm by 30.4 cm. She cut out as many squares as possible from the paper. The side of each square was 4 cm.
- How many squares did Hilda cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 30.4 ÷ 4
= 7 r 2.4
Number of squares that can be cut out lengthwise
= 44 ÷ 4
= 11 r 0
Total number of squares
= 11 x 7
= 77
(b)
Remaining breadth of the paper left = 2.4 cm
Area of the paper left
= 44 x 2.4
= 105.6 cm
2 Answer(s): (a) 77; (b) 105.6 cm
