Answer 1

$\huge \red {Hey\:mate}$

Here is the answer :- .

Let the lenght and breadth be 7x & 5x

Given perimeter = 480 m

as we know ,

Perimeter = 2 ( l + b )

Then , according to the question :-

480 = 2 (7x + 5x)

480 = 14x + 10x

480 = 24x

x = 480/24

x = 20

The value of X = 20

Length = 7 × 20 = 140 m

Breadth = 5 × 20 = 100 m

$\boxed {Dimensions = 140 × 100 m}$
