Whew photo. Hope this helps.
% damaged = (14 000/40000) * 100%
= 14/40 * 100%
= 0.35*100%
= 35%
-8*21
= -168
Hope this helped
The first thing you should do in this case is to draw the vertices in the Cartesian plane and join each of the points.
Then, to find the area of the figure you must first find the area of the rectangle and add it to the area of the parallelogram.
Area of the rectangle: Ar = (w) * (l)
Ar = (root ((6-4) ^ 2 + (1 - (- 2)) ^ 2)) * (root ((- 3-6) ^ 2 + (7-1) ^ 2))
Ar = (3.61) * (10.82)
Ar = 39
Parallelogram Area:
Ap = b * h
Ap = (root ((- 7 - (- 3)) ^ 2+ (7-7) ^ 2)) * (root ((- 7 - (- 7)) ^ 2+ (7-4) ^ 2) )
Ap = (4) * (3)
Ap = 12
Total area:
At = Ar + Ap = (39) + (12) = 51
answer: The area of the figure is: At = 51 Units ^ 2
Hello from MrBillDoesMath!
Answer:
12
Discussion:
The two triangles shown are congruent by the SAS postulate so the area of a single triangle is one-half that of the rectangle. That is,
Area = (1/2) * 24 = 12
Thank you,
