Answer:

Step-by-step explanation:
I'm never sure how far to go on these questions but I think what I'e done looks pretty nice. Essentially I simplified each radical, factored out each variable, combined the radicals after more simplification, and then picked the answer you were most likely looking for. I gave some alternatives in my work that are "simple" too, but the answer above is most likely I'd say.
Work is in the attachment, comment with any questions.
I believe the shorter sides are 5 feet and the longer ones are 10. This is because when you add up the two shorter sides as 10, and the other two as 20, then add them up to 30. That's the perimeter. For the area, you would do 10•5 to get 50 for the area
Answer: 28/125
Step-by-step explanation: To divide two fractions, flip the second fraction and multiply. The equation will be:
4/25 x 7/5
Multiply the numerators by the numerators and the denominators by the denominators.
4 x 7 = 28 (numerator)
25 x 5 = 125 (denominator)
Put into a fraction.
28/125
