Answer 1

⭐Given:

• Perimeter of a rectangle=20 cm

• Length(l) =7 cm

⭐To Find:

• Breadth (b) =?

⭐Solution:

Since,..

We know that,

Perimeter of a rectangle=2(l+b)

20=2(7+b)

20/2=7+b

10=7+b

b=10-7

b=3

Therefore,

The breath of the rectangle is 3 cm.

Answer 2

Answer:

The answer is 3cm.

Hope it helps.

Step-by-step explanation:

Perimeter=20cm

Length =7cm

P=2×(l+b)

20=2×(7+b)

20/2=7+b

10=7+b

b=10-7

b=3cm
