Question

length 35 cm
breadth ? pe
perimeter of rectangle 120 cm ​

Answer 1

Answer:

GIVEN :-

Length = 35cm

Perimeter = 120 cm

We have to find breadth!

════════════════

YOU SHOULD KNOW :-

Perimeter of rectangle :- 2( l + b)

════════════════

120 = 2( 35 + b)

$\implies$ 120 = 70 + 2b

$\implies$ 2b = 120 - 70

$\implies$ 2b = 50

$\implies$ b = $\dfrac{50}{2}$

$\implies$ b = $\boxed{\sf{25}}$

Therefore, breadth of given rectangle is 25 cm

Answer 2

Answer:

breadth = 25

Step-by-step explanation:

given , length = 35 cm , perimeter =120 cm ,

breadth =?

perimeter =2(length +breadth)

120cm= 2( 35 +breadth)

120 cm= 70 +2breadth

2breadth =120-70

2breadth = 50cm

so , breadth = 50 ÷2

. breadth = 25 cm
