the breadth of a rectangular court is 6m less than its length and it's perimeter is 68m. find the area of rectangular court.
please, help!


onkarsingh0149: let l = x and b = x - 6 then it's perimeter =68 ; 2(x +x-6) 68 ; 4x-12 =68 ; x =20 so l 20 and b =14 so area = 14x20 = 280 sq. units

amrit5g: ok but mine isnt wrong either
Ankur1516: let the length of rec. court- x and breadht is x-6 , perimeter- 68; 2(l+b)=68 (aq) = 2(x+x-6) =68 = 4x-12=68 ;;; x= 68+12 ÷ 4= 80÷2 = 40sq units

let the length of the court is x

then the breadth will be x-6

perimeter of a rectangle is 2(l+b)

a.q. 2{x+(x-6m)}=68m

= 2(x+x-6m)=68m

= 2(2x-6m)= 68m

=4x-12m=68m

=4x= 68m+12m

= 4x= 80m

=x= 80m/4

=x= 20m

l=20m

b=20m-6m=14m

area= lb

= 20m×14m= 280m^2

\textbf{\underline{\underline{Answer :-}}}

The area of the Rectangle is 280 sq.m

\textbf{\underline{\underline{Explanation :- }}}

\textsf{\underline{\underline{Given :}}}

The Perimeter = 68 m

Breadth = 6m less than its length

\textsf{\underline{\underline{To find :}}}

The area of the Rectangle

\textsf{\underline{\underline{Solution :}}}

\textsf{Consider the Length as x}

\textsf{So, Breadth = x - 6}

★ We know that : \boxed{\sf{Perimeter = 2(Length + Breadth)}}

\sf{\implies}2(x + x - 6) = 68

\sf{\implies}2x + 2x - 12 = 68

\sf{\implies}4x - 12 = 68

\sf{\implies}4x = 68 + 12

\sf{\implies}4x = 80

\sf{\implies}x =  \dfrac{80}{4}

\sf{\implies}x = 20

\textsf{Length of the Rectangle = 20 m}

Value of x - 6

\sf{\implies} 20 - 6

\sf{\implies} 14

\textsf{Length = 20 m}

\textsf{Breadth = 14 m}

\star Area of Rectangle

★ We know that : \boxed{\sf{Area = Length \times Breadth}}

\sf{\implies}20 \times 14

\sf{\implies}280

\textsf{Area = 280 sq.m}

\therefore The area of the Rectangle is 280 sq.m
