Question

The ratio of the length of a school ground to its width is 5: 2. Find the length if the width of the ground is 50 m.

Answer 1

Given- Ratio of length and width $=5:2$

width of the ground $=50m$

Let the length of school ground be $5x$

Then width of school ground will be $2x$

according to question-

width of the ground$=50m$

$$\begin{gathered} \Rightarrow 2x=50 \\ \Rightarrow x=\frac{50}{2} \\ \Rightarrow x=25 \end{gathered}$$

length of ground

$$\begin{gathered} =5x \\ =5\times 25(byu\sin gx=25) \\ =125m \end{gathered}$$

Hence length of ground is$125m$.
