Answer:
Length of rectangle = 28 cm
Width of rectangle = 12 cm
Step-by-step explanation:
Perimeter= 80cm
We are given Length:Width = 7:3
We can write them as:
Length =7x
Width=3x
We need to find length and width.
To find length and width we need to find value of x.
The formula used is: [tex]Perimeter= 2(Length+Width)[/tex]
Putting values and finding value for x
[tex]Perimeter= 2(Length+Width)\\80=2(7x+3x)\\40=10x\\x=\frac{40}{10} \\x=4[/tex]
So, length = 7x = 7*4 = 28
Width = 3x = 3*4 = 12
So, Length of rectangle = 28 cm
Width of rectangle = 12 cm
