Question

The perimeter of a rectangle is 10cm. If the lenght is 3⅔ cm , find its breadth​

Answer 1

$length = 3 \frac{2}{3} = \frac{3 \times 3 + 2}{3} \\ = \frac{9 + 2}{3} = \frac{11}{3} cm \\ perimeter \: of \: rectangle = 10 \\ 2(l + b) = 10 \\ \frac{11}{3} + b = 5 \\ b = 5 - \frac{11}{3} \\ = \frac{15 - 11}{3} \\ = \frac{4}{3} \\ 1 \frac{1}{3} cm$
