Answer:

Perimeter = 100 cm

Step-by-step explanation:

Let the breadth of the rectangle be x.

So, length will be 3x.

Area of rectangle = l x b

                        75 = 3x x x

                        75 = 3x^2

                         x^2 = 25

                         x = 5

Length = 3 x 25 = 75

Breadth = 25

Perimeter = l + b = 75 + 25 = 100 cm
