$here \: is \: your \: answer \\ perimeter \: of \: rectangle \: = 2(l + b) \\ now \: length \: = 10 \: cm \: and \: let \: the \: breadth \: be \: x \\ = perimeter \: of \: rectangle \: given \: = 30 \: cm \\ so \\ = 2(10 + x) = 30 \\ = 2 \times 10 + 2 \times x = 30 \\ = 20 + 2x = 30 \\ = 2x = 30 - 20 \\ = 2x = 10 \\ = x = \frac{10}{2} \\ = x = 5 \\ hence \: breadth \: is \: 5 \: cm \: \\ hope \: it \: helped \: \\ plz \: mark \: as \: brianliest \\ \\ stay \: home \: stay \: safe$
