I am a rectangle.

My perimeter is 80
Perimeter of the rectangle = 80 cm.

2 ( x + x) = 80

2 x x = 80

x = 80

x =

Breadth of rectangle = cm and Length of rectangle = cm​

Answer 1

Answer:

Breadth=10cm and length=30cm

Step-by-step explanation:

Length=3xbreadth

Perimeter of rectangle= 80cm

2(l+b)=80

2(3b+b)=80

2(4b)=80

4b=80/2

4b=40

b=40/4

10cm

--------------

Length=3 times breadth

Length= 3x10

=30cm

Therefore the length of the rectangle is 30cm and the breadth of the rectangle is 10cm.
