Question

Find the breadth of the rectangle whose perimeter is 360m
and length is 100cm

Answer 1

Answer:

perimeter of rectangle

=2(l+b)

given length l = 100 cm

perimeter = 360

2(l+b) = 360

2(100+b) = 360

100 + b = 360/2

b = 180 - 100

b = 80

Hence breadth = 80cm

Answer 2

Given: perimeter of rectangle $= 360m$

         length of rectangle $=100cm$

To find: breadth of rectangle

Step-by-step explanation:

Let length and breadth of a rectangle be l and b respectively.

$perimeter$ $of$ $rectangle$ $= 2(l+b)$

$2(l+b) = 360\\2(100+b)=360\\100+b=\frac{360}{2}\\ 100+b=180\\b=180-100\\b=80$

∴ breadth of given rectangle $=80cm$
