PSLE Anna had a rectangular piece of paper, 52 cm by 35.1 cm. She cut out as many squares as possible from the paper. The side of each square was 2 cm.
- How many squares did Anna cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 35.1 ÷ 2
= 17 r 1.1
Number of squares that can be cut out lengthwise
= 52 ÷ 2
= 26 r 0
Total number of squares
= 26 x 17
= 442
(b)
Remaining breadth of the paper left = 1.1 cm
Area of the paper left
= 52 x 1.1
= 57.2 cm
2 Answer(s): (a) 442; (b) 57.2 cm
