Question

Length and breadth of a recatngle are 10 cm and 5 cm respectively. Calculate the area of the rectangle.

• A. $15c{m}^2$
• B. $30c{m}^2$
• C. $20c{m}^2$
• D. $25c{m}^2$

Answer 1

The correct option is B $30c{m}^2$

Length of a rectangle = l = 10 cm
Breadth of a rectangle = b = 5 cm
As we know,
Area of rectangle = 2( l + b)

Let the area of a rectangle be $x$.

$\Rightarrow x=2(10+5)=2\times 15=30c{m}^2$

Hence, area of the rectangle is $30c{m}^2$
