PSLE Esther had a rectangular piece of paper, 55 cm by 29.3 cm. She cut out as many squares as possible from the paper. The side of each square was 5 cm.
- How many squares did Esther cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 29.3 ÷ 5
= 5 r 4.3
Number of squares that can be cut out lengthwise
= 55 ÷ 5
= 11 r 0
Total number of squares
= 11 x 5
= 55
(b)
Remaining breadth of the paper left = 4.3 cm
Area of the paper left
= 55 x 4.3
= 236.5 cm
2 Answer(s): (a) 55; (b) 236.5 cm
