Answer 2

Answer:

Width of the rectangle = 4.5cm

Step-by-step explanation:

Let the breadth of rectangle be 'x' cm

Then the length of rectangle will be '3x' cm

Perimeter of rectangle (P) = 36 cm

ATF

P=2(l+b)

or, 36 = 2(3x+x)

or, 36/2= 4x

or, 18/4 = x

x= 4.5

breadth(b)= x = 4.5cm

length (l) = 3x= 3*4.5= 13.5 cm
