Step-by-step explanation:
<u><em>I'm going to assume that these photocopies are proportional in relations to each other.</em></u>
If they're proportional, you can set up two proportions:
And cross-multiply:
Then solved for x and y:
Answer:
Step-by-step explanation:
I believe this is the correct answer. In order to check that my equations are correct I put in some dummy numbers.
a= 2
b=4
c=
I think 2,3,4 or B,C,D would be correct.
The area of a triangle is (b•h)/2
And the area of a rectangle and parallelogram would just be b•h
1) 8(6) = 48/2 =24
2) 9(10 2/3) = 96/2 =48
3) 19.2(2.5) = 48
4) 16(3) = 48
Hope this is right and hope it helps. Have a good day
