Question

perimeter of rectangle 800cm length 2.5m.breadth

Answer 1

Given ,

Perimeter of a rectangle = 800cm

Length of a rectangle, L = 2.5 m i.e. 250 cm

Breadth of a rectangle , B = ?

We know ,

Perimeter of a Rectangle = 2 ( L + B )

=> 800 = 2 ( 250 + B )

=> 400 = 250 + B

=> 400 - 250 = B

=> 150 = B

Thus , Required Breadth of the Rectangle = 150cm OR 1.5 m

Answer 2

perimeter of rectangle = 800 cm ( given)
Length of rectangle = 2.5 m
First we find
2.5m into cm = 25÷10×100
250cm.
800cm = 2 ( l + b ) cm
800cm= 2 (250 + b ) cm
800/2 = 250+b
400 =250+ b
400-250 = b
150 = b
So breadth is 150 cm.....
