$as \: we \: know \: perameter \: of \: rectngle = 2(length \ + beadth)$

$and \: also \: perimeter \: = 224cm$

$therefore \: we \: can \: write \: that 2(length + bredth) = 224cm$

let the length be l

and breadth is 55 cm

2(l + 55) = 224

$l + 55 = \frac{224}{2}$

l + 55 = 112

l = 112 - 55

l = 57

so the length of rectangle is 57 cm
