PSLE Julie had a rectangular piece of paper, 52 cm by 31.8 cm. She cut out as many squares as possible from the paper. The side of each square was 4 cm.
- How many squares did Julie cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 31.8 ÷ 4
= 7 r 3.8
Number of squares that can be cut out lengthwise
= 52 ÷ 4
= 13 r 0
Total number of squares
= 13 x 7
= 91
(b)
Remaining breadth of the paper left = 3.8 cm
Area of the paper left
= 52 x 3.8
= 197.6 cm
2 Answer(s): (a) 91; (b) 197.6 cm
