PSLE Jaslyn had a rectangular piece of paper, 53.4 cm by 28 cm. She cut out as many squares as possible from the paper. The side of each square was 2 cm.
- How many squares did Jaslyn cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out lengthwise
= 53.4 ÷ 2
= 26 r 1.4
Number of squares that can be cut out breadthwise
= 28 ÷ 2
= 14 r 0
Total number of squares
= 14 x 26
= 364
(b)
Remaining length of the paper left = 1.4 cm
Area of the paper left
= 1.4 x 28
= 39.2 cm
2 Answer(s): (a) 364; (b) 39.2 cm
