Answer 2

Answer:

Answer:Breadth=9cm

Answer:Breadth=9cmStep-by-step explanation:

Answer:Breadth=9cmStep-by-step explanation:Perimeter=30cm.

Length=6cm.

perimeter=2(l+b)

30=2(6+x)

30=2(6+x)30=12+2x

30=2(6+x)30=12+2x30-12=2x

30=2(6+x)30=12+2x30-12=2x18=2x

30=2(6+x)30=12+2x30-12=2x18=2xx=18/2

30=2(6+x)30=12+2x30-12=2x18=2xx=18/2So x=9cm.

30=2(6+x)30=12+2x30-12=2x18=2xx=18/2So x=9cm.Therefore the breadth is 9cm.
