Question

The ratio of length to breadth of a rectangular sheet is 9:5. If the breadth of the sheet is 15 cm find its length

Answer 1

Step-by-step explanation:

length to breadth of a rectangular sheet is 9:5,

breadth is 15cm

let length and breadth be 9x,5x respectively

15cm = 5x

$15 = 5x \\ 15 \div 5 = x \\ 3 = x$

9x = 9 * 3 = 21 cm

Answer 2

Answer:

$ratio \: of \: length \: to \: breadth = 9 \: ratio \: 5 \\ length = x \\ breadth = 15cm \\ according \: to \: the \: question \\ \frac{9}{5 } = \frac{x}{15} \\ by \: cross \: multiplication \\ 5 \times x = 9 \times 15 \\ x = \frac{9 \times 15}{5} \\ x = 9 \times 3 \\ x = 27cm$
