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

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
