PSLE Jaslyn had a rectangular piece of paper, 51.2 cm by 36 cm. She cut out as many squares as possible from the paper. The side of each square was 6 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
= 51.2 ÷ 6
= 8 r 3.2
Number of squares that can be cut out breadthwise
= 36 ÷ 6
= 6 r 0
Total number of squares
= 6 x 8
= 48
(b)
Remaining length of the paper left = 3.2 cm
Area of the paper left
= 3.2 x 36
= 115.2 cm
2 Answer(s): (a) 48; (b) 115.2 cm
