Question

The length of a rectangular plot is 3 times the breadth of the plot.If the breadth of the plot is b, form an equation for its length and the perimeter.

Answer 1

breadth=b
lenght=3b
peremeter=2(l+b)=2(3b+b)=2(4b)=8b

hope this will help you

Answer 2

Length = 3b and Perimeter=8b

Step-by-step explanation:

Let the breadth of the plot is b.

It is given that the length of a rectangular plot is 3 times the breadth of the plot.

Length of a rectangular plot = 3b

Perimeter of a rectangle is

$Perimeter=2(length+breadth)$

Perimeter of the given rectangular plot is

$Perimeter=2(3b+b)$

$Perimeter=2(4b)$

$Perimeter=8b$

Therefore, Length = 3b and Perimeter=8b.
