Answer 1

Answer:

Step-by-step explanation:

Let the breadth of the rectangle be xcm

Then it's length=x+5cm

Perimeter=2(length+breadth)

⇒70=2(x+(x+5))

⇒  

2

70

​

=2x+5

⇒2x+5=35

⇒2x=35−5=30

⇒x=

30

​

=15cm

Breadth=x=15cm and length=x+5=15+5=20cm

Answer 2

Step-by-step explanation:

20 cmLet the breadth of the rectangle be xcm

Then it's length=x+5cm

Perimeter=2(length+breadth)

> 70=2(x+(x+5))

70

= 2x+5→ 2x+5=35

→2x-35-5=30

⇒ X=

30

=15cm

Breadth=x=15cm and length=x+5=15+5=20cm
