Answer:

The perimeter of a rectangle is 36 cm, its breadth is 8 cm

Step-by-step explanation:

For a given rectangle

Perimeter (P) = 36 cm

length (L) = 10 cm

Now,

Perimeter (P) = 2 × (length + breadth)

P = 2 × (l + b)

36 = 2 × (10 + b)

36 = 20 + 2b

2b = 36 - 20

2b = 16

b = 16 ÷ 2

b = 8 cm

Thus, The perimeter of a rectangle is 36 cm, its breadth is 8 cm

<h2><u>Question</u>:-</h2>

The perimeter of a rectangle is 36 cm. If its length is 10 cm, find its breadth.

<h2><u>Answer</u>:-</h2>

<h3>Given:-</h3>

$\bullet$ Perimeter (P) of a rectangle is 36 cm.

$\bullet$ Length (L) of a rectangle is 10 cm.

Breadth (B) of a rectangle.

<h2>Solution:-</h2>

We know,

P = 2(L + B)

So,

36 = 2(10 + B)

36 = 20 + 2B

36 - 20 = 2B

16 = 2B

B = 16/2 = 8 cm.

<h3>Breadth (B) of a rectangle is <u>8</u><u> </u><u>cm</u>. [Answer]</h3>

Which expression is the factorization of x2 + 10x + 21? (x + 3)(x + 7) (x + 4)(x + 6) (x + 6)(x + 15) (x + 7)(x + 14)

Vadim26 [7]

Answer: First option.

Step-by-step explanation:

You need to remember that to factorize the given expression $x^2+10x+21$ , you need to choose two numbers that when you add them you get "10" and when you multiply them you get "21".
