Question

The length of a rectangular hall is $5$ metres more than its breadth. If the breadth of the hall is $25$ metres, then the area of the hall is _________ .

• A. $150m^2$
• B. $225m^2$
• C. $750m^2$
• D. $850m^2$

Answer 1

The correct option is C $750m^2$

$\Rightarrow$ Here, $b=25m$ and length is 5 m more than breadth, so $l=25+5=30m$.

$\Rightarrow$ Area of the rectangular hall = $l\times b$

$\Rightarrow$ Area of the rectangular hall = $30m\times 25m$

$\therefore$ Area of the rectangular hall = $750m^2$
