Question

Length and width of a field are in the ratio 5:3 .if the width is 42m, then it's length is.

Answer 1

Given :-

Lenth and width ratio = 5:3

Width is = 42m

To find :-

Length.

Step By Step Explaination :-

Let the ratio is given is 5:3

and the width is = 42m

be represented as,

=> 5/3 = x/42

=> x= 42x5/3

=> x= 14x5

=> x= 70

So,the value of Length is 70m.

ans.

Answer 2

The length of the given field is 70 m.

Given:

The ratio of length and width is 5:3

The width of the field is 42 m.

To Find:

we need to find the length of the field.

Solution:

As the given ratio is 5:3, let us assume

The length is 5x

The breadth will be 3x.

As the breadth of the field is given as 42m

$3x = 42$

$x = \frac{42}{3}$

$x = 14m$

We got the value of x. Now substitute the value in the length we assumed.

$= 5x$

$= 5(14)$

$= 70m$

Therefore, the length of the field is 70m.
