step by step

Answer 1

$\underline{ \blue { Dimensions \:of \: a \: Rectangular \:Table \:Mat : }}$

$Length (l) = 12 \: cm, \: Breadth (b) = 8 \:cm$

$\red{ Length \:of \:a \: ribbon \: needed } \\= Perimeter \:of \:the \: table \:mat \\= \pink { 2(l+b)} \\= 2( 12 \:cm + 8\:cm ) \\= 2 \times 20 \:cm \\= \green {40 \:cm}$

$\underline{ \blue { Dimensions \:of \: Anays \: Garden: }}$

$Length (l) = 11\: m, \: Breadth (b) = 5 \:m$

$\red{ Length \:of \:a \: Fence } \\= Perimeter \:of \:the \: Garden \\= \pink { 2(l+b)} \\= 2( 11 \:m + 5\:m ) \\= 2 \times 16 \:m \\=\green { 32 \:m}$
