Question

What is the area of the table whose sides measure 1m 20 cm in length and 2m 50 cm in breadth?

• A. 3 m 70 cm
• B. 3 m 50 cm
• C. $3.7m^2$
• D. $3m^2$

Answer 1

The correct option is D $3m^2$

Length (l) = 1 m 20 cm = $(1+\frac{20}{100})m=1.2m$
Breadth (b) = 2 m 50 cm = $(2+\frac{50}{100})m=2.5m$
Area = $l\times b=1.2\times 2.5=3m^2$
