Question

the perimetre of a rectangular field is 360 m and its breadth is 75 m. find its length

Answer 1

2×(l+b)=360
2×(l+75)=360
2l+150=360
2l=360-150
l=110/2
l=55m

Answer 2

Here is ur answer............

Given breadth of the rectangular field = 75m

perimeter = 360m

let l be the length of the rectangular field

==>2( l + b ) = 360

==>2 ( l + 75 ) = 360

==> l + 75 = 360/2 = 180

==> l = 180 - 75 = 105
