Explanation:
Correct option:1
Solution:Given that a plank of wood 4.25 m long and 3.4 m wide is to be cut into square pieces of equal size.
The problem requires cutting the plank into square pieces with no wastage.
The dimensions of the plank are 4.25 m by 3.4 m.
The largest possible square size, we calculate the HCF of 4.25 m and 3.4 m.
The HCF of 425 cm and 340 cm is 85 cm.
Thus, the largest square piece is 85 cm x 85 cm.
The number of such squares= 425 cm / 85 cm = 5
Along the width: 340 cm / 85 cm = 4
Total number of squares = 5 * 4 = 20.
Correct Answer: Option 1 - 20 (The actual answer should be 20, not in the provided options)
