What is the area of the white border?
Lina20 [59]

Answer:

A_{white} = 119\ cm^2

Step-by-step explanation:

<u>Step 1:  Determine the area of the black area</u>

A = l * w

A = 8\ cm * 2\ cm

A = 16\ cm^2

<u>Step 2:  Determine the area of the entire white and black area</u>

A = l * w

A = 9\ cm * 15\ cm

A = 135\ cm^2

<u>Step 3:  Determine the difference to just get the white area</u>

A_{white} = 135\ cm^2 - 16\ cm^2

A_{white} = 119\ cm^2

Answer: A_{white} = 119\ cm^2

Select the polynomial that is a perfect square trinomial. 9x2 9x 1 36b2 − 24b 8 16x2 24x 9 4a2 − 10a 25.
alexgriva [62]

The polynomial that is a perfect square is 16x^2 + 24x +9. Option C shows the polynomial which is a perfect square.

<h3>What is square?</h3>

The square can be defined as a two-dimensional figure that has 4 equal sides.

Given are the equations of the areas of the polynomial.

Option C: 16 x^2 + 24x +9

We can write the above equation as,

(4x)^2 + 2 \times 4x \times 3 + (3)^2

(a+b)^2 = a^2 + 2ab+b^2

Here a = 4x  and b = 3, so

16x^2 + 24x+9 = (4x+3)^2

The simplification of the area of a polynomial is (4x+3)^2 which represents the area of a square.

Hence the polynomial that is a perfect square is 16x^2 + 24x +9. Option C shows the polynomial which is a perfect square.

To know more about the area of the square, follow the link given below.
