Question

The length of a rectangle field are in ratio 5: 3 if it's perimeter is 64m find the dimension

Answer 1

let the length =5x and breadth 3x
$2(l + b) = perimetre \: of \: rectangle \\ 2(5x + 3x) = 64 \\2( 8x) = 64 \\ 16x = 64 \\ x = 4$
length =5x=20
breadth =3x=12

Answer 2

Hello friend,

Length:Breadth = 5:3

Length=5x

Breadth=3x

Perimeter=64cm

=>2(5x+3x)=64

=>16x=64

=>x=4

Therefore,

Length = 20cm

Breadth = 12cm

Hope you have got the trick and please mark the answer as the brainliest.
