What is the area of the white border?

Lina20 [59]

Answer:

$A_{white} = 119\ cm^2$

Step-by-step explanation:

Step 1: Determine the area of the black area

$A = l * w$

$A = 8\ cm * 2\ cm$

$A = 16\ cm^2$

Step 2: Determine the area of the entire white and black area

$A = l * w$

$A = 9\ cm * 15\ cm$

$A = 135\ cm^2$

Step 3: Determine the difference to just get the white area

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

$A_{white} = 119\ cm^2$

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