Question

pls tell the answer ma'am or sir​

Answer 1

Given :

• Perimeter of the floor is 60 m .
• Length is 4 times is Breadth

To Find :

• Find the Dimensions

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

SolutioN :

$\dag$ Formula Used :

• ${\underline{\boxed{\sf{ Perimeter = 2 \bigg( Length + Breadth \bigg) }}}}$

$\dag$ According to the Question :

$\longmapsto$ Let the Breadth be y m .So :

$\qquad \; {\qquad{\sf{ Breadth = y \; m }}}$

$\longmapsto$ Length is 4 times the Breadth .So :

$\qquad \; {\qquad{\sf{ Length = 4y \; m }}}$

$\dag$ Calculating the Value of y :

${\longmapsto{\sf{ \; \; Perimeter = 2 \bigg( Length + Breadth \bigg) }}} \\ \\ \\ \ {\longmapsto{\sf{ \; \; 60 = 2 \bigg( y + 4y \bigg) }}} \\ \\ \\ \ {\longmapsto{\sf{ \; \; 60 = 2 \times 5y }}} \\ \\ \\ \ {\longmapsto{\sf{ \; \; 60 = 10y }}} \\ \\ \\ \ {\longmapsto{\sf{ \; \; \dfrac{60}{10} = y }}} \\ \\ \\ \ {\longmapsto{\sf{ \; \; \cancel\dfrac{60}{10} = y }}} \\ \\ \\ \ {\longmapsto \; {\underline{\boxed{\pmb{\sf{ y = 6 }}}}}} \; {\purple{\pmb{\bigstar}}}$

$\dag$ Calculating the Domensions :

• Breadth = y = 6 m
• Length = 4y = 4(6) = 24 m

$\therefore \;$ Length of the Rectangle is 6 m and its Breadth is 24 m .
