$\bullet{\leadsto} \: \sf Area \: of \: the \: field \: = \: 3840m^{2}.$

$\bullet{\leadsto} \: \textsf{Let the length and breadth of the field be x.}$

$\bullet{\leadsto} \: \pink{\tt Then, \: Length \: = \: 10x.}$

Answer 2

Given:

• Ratio of length and width is 10:6

Area of the field is 3840 m².

To Find :

• Difference between the length and width.

Solution:

Let Length of field be = 10x

Let Breadth of field be = 6x

Using Formula :

Area of Rectangle = 1 x w

Putting Values:

3840 = 10x x 6x

3840 = 60x2

64 = x

→→→→ x = 8 m

Value of x is 8 m..

Therefore:

Length of field = 10(8)

80 m

Width of field = 6(8)

→→→→ 48 m

Now

Difference between Length and Width :

80-48

32 m
