Set up a porportion,
3/5 hours / 2/5 square yards
1 hour / x square yards
simplify by cross multiplying
3/5x <span>= 2/5(1).
</span>3/5x <span>= 2/5.
</span> 3/5/3/5x = <span>2/5/3/5
x </span><span>= 10/15
</span>x <span>= 2/3
</span><span>
so she can paint </span><span>2/3 square yards in 1 hour. hope this helps!</span><span>

Answer:
22 meters
Step-by-step explanation:
What we know:
Side AB is 7 1/2 m long, Side BC is 2 1/4 m long, and Side DE is 1 1/4 m long.
Saying Sides AH and FG are the same as Sides DE and BC respectively, we can add another 3 1/2 m to the perimeter.
If CD, EF and GH are each 1/3 of AB, then 7 1/2 is added again.
7.5 + (2.5 * 3) * (2.25 * 2) + (1.25 * 2)
7.5 + 7.5 + 4.5 + 2.5
15 + 7
The perimeter is 22 meters.
