b is two fifths of c, so we make this a ratio with c = 1.
The ratio of b:c is 2/5 : 1
We also have 4a = 3c, rewrite this ratio so c is 1 by dividing both sides by 4,
so we get the ratio of a to c as 3/4 : 1
Now we get the a:b:c ratio of 3/4 : 2/5 : 1 now we can change the fractions to whole numbers, first by multiplying the 3 numbers by 4 to get get rid of the denominator of 4 in a:
3 : 8/5 : 4
Now multiply the 3 numbers by 5 to remove the denominator of 5 in b:
15 : 8 : 20
Now we can check using the equations:
b is 2/5 of c: 20 x 2/5 = 40/5 = 8 This is true.
4a = 3c: 4(15) = 3(20) = 60 = 60, this is also true.
The ratios is 15 : 8: 20

Answer:
<u>1728 in²</u>
Step-by-step explanation:
For the area of B, you need to find the length and width (height and base, whatever you want to call it).
For the height, you would need to do: 144 - 36 - 24 - 36 = <u>48 inches</u>
For the base, you would need to do: 60 - 24 = <u>36 inches</u>
Now you multiply the base and height to get the area: 48 x 36 = <u>1728 in²</u>
