Question

the ratio of length to breadth of a rectangular sheet is 9:5, if breadth is 15cm. find its length ​

Answer 1

Let Length of rectangle L and Breadth is b .

• L / b = 9/5

or

• L = 9x , b = 5x

or

• 5L = 9b... we will use this equation.

Breadth = 15 cm ( given )

5L = 9b

5L = 9 × 15

5L = 135

L = 135/5

L = 27 cm

therefore Length of rectangle is 27 cm.

hope it helps you

Answer 2

• As per data given in the question, we have to determine the length of rectangle.

       Given data:- Ratio of length to breadth $9:5.$

       To find:- the length of rectangle.

        Solution:-

        Let the length of rectangle be $x.$

        So, the ratio of length to breadth=$x:15cm.$

       As per the given condition,

       $\Rightarrow x:15=9:5\\\Rightarrow x\times5=15\times9\\\Rightarrow 5x=135\\\Rightarrow x=\frac{135}{5}=27cm.$

      Hence, the length of rectangle will be $27cm.$
