1.	Length and breadth of a rectangular wire are 9 cm and 7 cm respectively. If the wire is bent into a square find the length of its side
Answer» $\underline { \blue { Dimensions \:of \: a \: rectangular \:wire :}}$ $Length (l) = 9 \:cm , \: breadth (b) = 7 \:cm$ $Let \: \pink { Length \: of \: the \:square \:side =a }$ /* ACCORDING to the PROBLEM GIVEN */ $\orange { Perimeter_{(square )}} = \blue { Perimeter_{(rectangle )}}$ $\implies 4a = 2(l+b)$ $\implies 4a = 2( 9 \:cm + 7 \:cm )$ $\implies 4a = 2\times 16 \:cm$ $\implies a =\frac{ 32\:cm}{4}$ $\implies a =8\:cm$ THEREFORE., $\red { Length \: of \: the \:square \:side}\green {=8\:cm}$ •••♪
