Question

How many square pieces can be cut from a metal sheet of length 4 m and breadth 2.5 m if the side of the square piece is 25 cm.
1. 480
2. 160
3. 400
4. 120

Answer 1

Correct Answer - Option 2 : 160

Given:

Length is 4m and Breadth is 2.5m

Side of a square is 25cm

Concept Used:

1 m = 100 cm

Formula Used:

Area of a rectangle = Length × Breadth

Area of a square = (Side)²

Calculation:

4m = 400cm and 2.5m = 250 cm

Area of a rectangle,

⇒ 400 × 250

⇒ 1,00,000

Area of a square,

⇒ (25)²

⇒ 625

Number of squares that can be made,

⇒ 1,00,000/625

⇒ 160

∴ Number of squares made is 160.
