1.	The perimeter of rectangle is 20 cm. If the length of on side of the rectangle is 6 cm, then its breadth will be
Answer» Given : PERIMETER of RECTANGLE = 20cm Length of Rectangle = 6cm To Find : Breadth of Rectangle Solution : $\longmapsto\tt{Perimeter=20cm}$ $\longmapsto\tt{Length=6cm}$ Using Formula : $\longmapsto\tt\boxed{Perimeter\:of\:Rectangle=2(l+b)}$ Putting Values : $\longmapsto\tt{20=2(6+b)}$ $\longmapsto\tt{\cancel\dfrac{20}{2}=6+b}$ $\longmapsto\tt{10=6+b}$ $\longmapsto\tt{10-6=b}$ $\longmapsto\tt\bold{b=4cm}$ So , The Breadth of Rectangle is 4cm.. ━━━━━━━━━━━━━━━━━━━━ VERIFICATION : $\longmapsto\tt{20=2(6+4)}$ $\longmapsto\tt{20=2(10)}$ $\longmapsto\tt\bold{20=20}$ HENCE VERIFIED
