Question
A rectangle has length 40 cm and breadth 20 cm. How many squares with side 10 cm can be formed from it
✓
Answer
Area of rectangle $=($ length $\times$ breadth $)$ units ${ }^2$ Length $=40 cm$ Breadth $=20 cm$
$\therefore$ Area $=(40 \times 20) cm ^2$
$=800 cm ^2$ Area of rectangle $=800 cm ^2$ Area of square $=($ side $\times$ side $)$ units ${ }^2$
side $=10 cm$ Area of square $=(10 \times 10) cm ^2$
$=100 cm ^2$ Required number of squares $=\frac{\text { Area of Rectangle }}{\text { Area of } 1 \text { square }}$
$=\frac{800 cm ^2}{100 cm ^2}$
$=8$
8 squares can be formed.
