Answer:11) Length = 75 cm

Breadth = 25 cm

Explanation:Let assume that length is x and breadth is y. then,

Given,

Perimeter of rectangle = 200 cm

x = 3 (y)

x = 3y …(eq 1)

We know that,

Perimeter of rectangle = 2 ( x + y)

200 cm = 2 ( x + y) …(given)

200 cm = 2 (3y + y) …(from eq 1)

100 cm = 4y

100/4 = y

y = 25 cm

Therefore we get y putting in equation one.

x = 3y

x = 3 (25) cm

x = 75 cm

Hence, Length, x = 75 cm and Breadth, y = 25 cm.

Thankyou

I hope it is helpful to you.

Answer:Ok

Step-by-step explanation:Length = 3x

Breadth = x

8x= 200

X= 200/8

X =25

Breadth = 25cm

Length = 75cm
