Question

Pls solve Q19 with proper steps

Answer 1

Answer:

3x + 4y

Step-by-step explanation:

(19)

Given Area of square = 9x² + 24xy + 16y²

                                    = (3x + 4y)².

We know that Area of square = s²

⇒ (3x + 4y)² = (s)²

⇒ s = 3x + 4y.

Therefore, the side of the square = 3x + 4y.

Hope it helps!

Answer 2

Hola

Here is your answer


Area of square - 9x² + 24xy + 16y²

By factorising this using the identity

(a + b)² - a² + 2ab + b²

Thus

We get ( 3x + 4y)²

We know area of square = side × side

Thus each side of square will be

3x + 4y

Hope it helps
