Question

the perimeter of a llgm is 240cm the ratio of the breadth to its lenght is 3:5 find the dimensions of the llgm​

Answer 1

Step-by-step explanation:

Let the length be 5x

let breadth be 3x

perimeter = 2(L+B)=240

2(5x+3x)=240

2×8x=240

16x=240

=15

length= 5x

= 5×15

75

breadth =3x

3×15

45
