Using the formula for area for a parallelogram, A=BH, where A is area, B is Base, and H is height, you follow that. So in this case, you would want to find one of the area's then multiply it by 4. So for the area you get 20.52 meters. If you multiply it by 4, you get 82.08 meters. Have a nice day!
Answer:
<h2>BR ≈ 49.0</h2>
Step-by-step explanation:
Use cosine:
![cosine=\dfrac{adjacent}{hypotenuse}](https://tex.z-dn.net/?f=cosine%3D%5Cdfrac%7Badjacent%7D%7Bhypotenuse%7D)
We have
![adjacent=42\\hypotenuse=BR\\\alpha=31^o](https://tex.z-dn.net/?f=adjacent%3D42%5C%5Chypotenuse%3DBR%5C%5C%5Calpha%3D31%5Eo)
![\cos31^o\approx0.8572](https://tex.z-dn.net/?f=%5Ccos31%5Eo%5Capprox0.8572)
Substitute:
![\dfrac{42}{BR}=0.8572](https://tex.z-dn.net/?f=%5Cdfrac%7B42%7D%7BBR%7D%3D0.8572)
<em>cross multiply</em>
<em>divide both sides by 8,572</em>
![BR=\dfrac{420,000}{8,572}](https://tex.z-dn.net/?f=BR%3D%5Cdfrac%7B420%2C000%7D%7B8%2C572%7D)
![BR\approx49.0](https://tex.z-dn.net/?f=BR%5Capprox49.0)
Answer:
2nd option
Step-by-step explanation:
Repeatedly divide by 2 until the value 1 is reached
32 ÷ 2 = 16
16 ÷ 2 = 8
8 ÷ 2 = 4
4 ÷ 2 = 2
2 ÷ 2 = 1 ← finish here
Then
32 = 2 × 2 × 2 × 2 × 2
