Answer:
The area of the shaded figure is:
Step-by-step explanation:
To obtain the area of the shaded figure, first, you must calculate this as a rectangle, with the measurements: wide (4 units), and long (6 units):
- Area of a rectangle = long * wide
- Area of a rectangle = 6 * 4
- Area of a rectangle = 24 units^2
How the figure isn't a rectangle, you must subtract the triangle on the top, so, now we calculate the area of that triangle with measurements: wide (4 units), and height (2 units):
- Area of a triangle =
![\frac{wide*height}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bwide%2Aheight%7D%7B2%7D)
- Area of a triangle =
![\frac{4*2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B4%2A2%7D%7B2%7D)
- Area of a triangle =
![\frac{8}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B2%7D)
- Area of a triangle = 4 units^2
In the end, you subtract the area of the triangle to the area of the rectangle, to obtain the area of the shaded figure:
- Area of the shaded figure = Area of the rectangle - Area of the triangle
- Area of the shaded figure = 24 units^2 - 4 units^2
- <u>Area of the shaded figure = 20 units^2</u>
I use the name "units" because the exercise doesn't say if they are feet, inches, or another, but you can replace this in case you need it.
Answer:
21.6 or 22
Step-by-step explanation:
Triangles have same angles. This means that they are proportion.
50/27 = 40/x
when you cross multiply to solve x, 50x = 1080
so x = 21.6
If you have to nearest whole number, it will be 22
Answer:
90 cubic inches
Step-by-step explanation:
Actual = 6 feet.
Measure = 5.49 feet
Error = 6 - 5.49 = 0.51
% Error = (Error / Actual) * 100%
= 0.51/6 * 100% = 8.5%
