This figure is four congruent triangles, so we just need to find the area of one, then multiply it by 4.
The area of a triangle is (1/2)bh where <em>b</em> is the base length and <em>h</em> is the height. In this case, b=21 and h=16
A = (1/2)bh
(1/2)·21·16
(1/2)·336
168 ← This is the area of one triangle, so then we multiply it by four:
4 · 168 = 672 in²
Answer:
The factory made2 batches of granola bars.
Explanation:
1/5 plus 1/5 is 2/5 and it takes the factory 1/5 of a barrel to make 1 batch of granola bars.
Answer:
(2, - 5)
Explanation:
The line y = -1 is horizontal: parallel to the y-axis.
The point B (2,3) is above the line y = - 1 at a distance equal to the y-coordinate of B (y = 3) less - 1:
Δy = 3 - ( - 1) = 4
When the point B (2,3) is reflected over the line y = -1, the x-coordinate does not change. The image will be 4 units down the line y = -1, thus the y-coordinate will be - 1 - 4 = - 5.
Hence, the coordinates of the vertex B' are x = 2, y = - 5: (2, - 5).
Answer:

Step-by-step explanation:
Hope it helps!
check the picture below, you can pretty much count the units off the grid.
recall that A = (1/2)bh.
