Answer:
1,200
Step-by-step explanation:
20 X 12 X 5 = 1,200
C = 2 * 3.14 * 4 = 25.1 to nearest tenth ( 1 decimal place)
W=2L-3
W*L=193
replace W with 2L-3: (2L-3)L=193
2L^2-3L-193=0
Cannot factor
are you sure the numbers are correct?
If it cannot be factored, use the quadratic formula to find out L, then you can find out W
use the Pythagorean theorem to find the diagonal. I don't see an easier way.
12/20 can be simplified to 3/5
