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

Answer:

If two sides of a triangle are unequal, the angle opposite to the longer side is larger (or greater). You may prove this theorem by taking a point P on BC such that CA = CP.

Step-by-step explanation:

That's how you can prove which side is bigger

Well each ladder has 30, and then it depends on how each person climbs their ladder. One climb at the rate of -2 per second. The other climb at the rate of 1 per second. Just x is equal to 1, that's why I didnt put 1x.
Equation: 30 + -2x = 30 + x
