Question

The ratio of length and width of a school ground is 5:2.Find the length, if the width is 40 metres​

Answer 1

⏬ ANSWER ⏬

Let the length of the school ground be 5x

and the width of the school ground be 2x

Now, Acc. to the quesn.

=> 2x = 40

=> x = 40/2

=> x = 20

Therefore, Length of the school ground = 5×20

= 100 metres

Answer 2

$\huge\boxed{ \mathfrak \red{Solution:-}}$

Let the common ratio be x

$\boxed{ \mathfrak \red{length = 5x}}$

$\boxed { \mathfrak \green{breadth = 2x}}$

Now, according to the question

$\boxed{ \bold\pink{2x = 40}}$

$\boxed{ \bold \pink{ \implies \: x = \frac{40}{2} }}$

$\bold \pink{ \implies \: x = 20 }$

Now,

$\boxed{ \bold\orange{breadth = 2 \times 20 = 40\: m}}$

$\boxed{ \bold \green{length = 5 \times 20 = 100\: m}}$
