Question

A table-top measures 3 m by 2 m 50 cm. What is its area in square metres?

• A. $7.5m^2$
• B. $7m^2$
• C. $6m^2$
• D. $8.5m^2$

Answer 1

The correct option is A $7.5m^2$

Area of reactangle = Length $\times$ Breadth

Here Length = 3m and
breadth = 2m 50 cm = 2.5 m (1 m = 100 cm )

$\therefore$ Area of the table top = 3 $\times$ 2.5
$=7.5m^2$
