The area of the whole figure:
6cm * 12cm = 72cm²

The area of the small, triangular, white figure:
\frac{2cm*8cm}{2}=8cm^2

The area of the shaded figure:
72cm² - 8cm² = 64cm²

Answer:

l = 2.25 cm

Step-by-step explanation:

given l is inversely proportional to w² then the equation relating them is

l = \frac{k}{w^2} ← k is the constant of proportion

(i)

to find k use the condition w = 1.5 , l = 16 , then

16 = \frac{k}{1.5^2} = \frac{k}{2.25} ( multiply both sides by 2.25 )

36 = k

l = \frac{36}{w^2} ← equation of proportion

(ii)

when w = 4 , then

l = \frac{36}{4^2} = \frac{36}{16} = 2.25 cm

A 24 foot ladder is placed against a building at an angle of 75⁰. How far is the bottom of the ladder from the building?
yanalaym [24]
24ft is the hypotenuse, at an angle of 75<span>⁰, and we need to find the adjacent.

We use cos(), which is adjacent divided by hypotenuse.

Therefore, we can find the adjacent by doing:

25 * cos(75) = 6.47ft

Round the answer however you like.</span>
