Question

the perimetre of a rectangular picture frame is 500cm.if its length is 190cm find its breadth

Answer 1

Perimeter of a rectangle = 2 ( length + breadth )
500 = 2 ( 190+ breadth )
250 = breadth +190
Therefore,
Breadth = 60 cm.

Answer 2

perimeter of a rectangle=2(l+b)
500=2(190+b)
500/2=190+b
250=190+b
250-190=b
60=b
therefore breadth =60cm
