The area is the area of 2 pairs of congruent triangles and one rectangle. Use the formulas for the areas of these figures, then add results.
Front triangle area (A = (1/2)bh)
.. = (1/2)(16 m)*(25 m) = 200 m^2
Right side triangle
.. = (1/2)(22 m)*(24 m) = 264 m^2
Base (A = lw)
.. = (16 m)*(22 m) = 352 m^2
Total area
.. 2*front triangle +2*side triangle +base
.. = 2*200 m^2 +2*264 m^2 +352 m^2
.. = 1280 m^2
Answer:
Step-by-step explanation:
-356.1 + 258.6 = -97.5
Imagine a long timeline with 0 in the middle, on the left we have -356.1 and on the right we have 356.1. Adding numbers makes the timeline move right.
Starting from the left, add (+) 258.6 to the number (moving right along the timeline). As 356 is larger than 258, the scale does not reach 0 yet and therefore the number must be negative.
Using this logic, the answer is 97.5
Answer:
Top row: [1 0 0 | 650}
Middle row: [0 1 0 | -400]
Bottom row: [0 0 1 | -1100]
Step-by-step explanation:
When you put an augmented matrix in RREF for, you have to have only 1's diagonal and 0's everywhere else on the left side of the bar.
