Question

The top of a table measures 2 m 25 cm by 1 m 20 cm. Find its area in square metres.

Answer 1

Length of the table = 2 m 25 cm
= (2 + 0.25) m (100 cm = 1 m)
= 2.25 m
Breadth of the table = 1 m 20 cm
= (1 + 0.20) m (100 cm = 1 m)
=1.20 m
Area of the table = (Length × Breadth) sq units
= (2.25 × 1.20) m²

= $(\frac{225}{100}\times \frac{120}{100})$ m²
= 2.7 m²
