Answer:
Is shaded 5/8 of the area of the rectangle
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The area of triangle ABC represent 1/4 of the total area
The area of triangle CDE represent 1/8 of the total area
The shaded region is composed by one triangle equal to triangle ABC and three triangles equal to triangle CDE
so
The area of the shaded region is equal to
![(1/4)(1)+(1/8)(3)=(1/4)+(3/8)=(2/8)+(3/8)=5/8](https://tex.z-dn.net/?f=%281%2F4%29%281%29%2B%281%2F8%29%283%29%3D%281%2F4%29%2B%283%2F8%29%3D%282%2F8%29%2B%283%2F8%29%3D5%2F8)
therefore
Is shaded 5/8 of the area of the rectangle
Answer:
Surface area of the cube =
Step-by-step explanation:
Given shape in figure 1:
Cube with edge length = 5 cm
To find the surface area of the cube.
Solution:
The surface area of a cube is given by the formula:
![Surface\ Area = 6a^2](https://tex.z-dn.net/?f=Surface%5C%20Area%20%3D%206a%5E2)
where
represents the length of the edges of the cube.
For the given cube ![a=5\ cm](https://tex.z-dn.net/?f=a%3D5%5C%20cm)
Plugging
in the formula to find the surface area of the cube.
![Surface\ Area = 6(5)^2](https://tex.z-dn.net/?f=Surface%5C%20Area%20%3D%206%285%29%5E2)
∴ ![Surface\ Area = 6\times 25 = 150\ cm^2](https://tex.z-dn.net/?f=Surface%5C%20Area%20%3D%206%5Ctimes%2025%20%3D%20150%5C%20cm%5E2)
The rest of the question: What is the area?
===============================================================
The area of the parallelogram = base × corresponding height
The base = 9 units
corresponding height = 2/3 units
<u>So, Area = 9 × 2/3 = 6 units</u>
