PSLE Kimberly had a rectangular piece of paper, 72 cm by 35.2 cm. She cut out as many squares as possible from the paper. The side of each square was 2 cm.
- How many squares did Kimberly cut out?
- What area of the paper was left?
(a)
Number of squares that can be cut out breadthwise
= 35.2 ÷ 2
= 17 r 1.2
Number of squares that can be cut out lengthwise
= 72 ÷ 2
= 36 r 0
Total number of squares
= 36 x 17
= 612
(b)
Remaining breadth of the paper left = 1.2 cm
Area of the paper left
= 72 x 1.2
= 86.4 cm
