misti786 · Answer

let the dimension is x so 5x, 3x

misti786 · Answer

the perimeter of a rectangle is 2(length+width), where length is 5x and width is 3x), and the equation would be 2(5x+3x)=80, now you can solve the equation and find the x, then substitute the x and you will find the dimension.

welshfella · Answer

the ratio 3:5  means that  the width = 3 / 5  of the length.
so if the length is x then the width is (3/5)x  = 0.6x

@welshfella ......can u show me how to do it give all  the work and the answer so therefore next time i know how to do it next time i end up doing a question like this?

djbreezy · Answer

or @misti786 ??

misti786 · Answer

so 2(8x)=80
16x=80 divide both side by 16
x=5
Therefore the length is 3*5=15 and width is 5*5=25

Thx

welshfella · Answer

well the length is 25 and width 15  - that was just a typo.

welshfella · Answer

by definition, length is greater than width.
