Answer 2

Given :

• Breadth of the Rectangle is "b" m .
• The length of the hall is 7 metres less than 4 times the breadth .

To Find :

• Find the Length

$\\ \qquad{\rule{200pt}{2pt}}$

$\dag$ Calculating the Length :

$\longmapsto$ The Breadth is b cm .So :

$\qquad \; {\pmb{\sf{ Breadth = b \; m }}}$

$\longmapsto$ Length is 7 m less than 4 times the Breadth .So :

$\qquad \; {\underline{\boxed{\pmb{\sf{ Length = 4b - 7 \; m }}}}} \; {\red{\pmb{\bigstar}}}$

$\therefore \;$ Length of the Rectangle is 4b - 7 m .

$\\ \qquad{\rule{200pt}{2pt}}$
