Question

The perimeter of a rect
rectangular sheet is 100cm
If the length is 35cm
find its breadth

.​

Answer 1

Perimeter= 100cm

Length= 35cm

Perimeter= 2(l+b)

100= 2(35=b)

\frac{100}{2}=35+b

50= 35+b

b=50 - 35= 15cm

Therefore, breadth= 15cm

Area= l\times b=35cm\ \times\ 15cm

=525cm^2

Answer 2

Step-by-step explanation:

Given : Perimeter Of a Rectangular Sheet 100 cm

Length = 35 cm

Find : Breadth

Solutions :

Let The Length is 1

Breadth = b of Rectangular

Now, Applying Perimeter Formula 2 ( l + b)

Perimeter Of Rectangular = 2 ( l + b)

100 = 2 ( 35 + b) ( Transpoising 2 To L. H. S)

100/2 = 35 + b

50 = 35 + b

b = 50 - 35 ( Transpoising 50 to L. H. S)

b = 15 cm

The Breadth Is 15 cm
