1. Perimeter
22a + 2(6a + 8) -4 = p
[I got 22a from 12a + 10a]
2. If p = 250, what is a?
22a + 2(6a + 8) - 4 = 250
Distributive property
22a + 12a + 16 - 4 = 250
Add like terms
34a + 12 = 250
Subtract 12 by both sides
34a = 238
Divide 34 by both sides
a = 7

In 10 minutes it 600 seconds
3/7 + 2/3
3/7 x 3/3 = 9/21
2/3 x 7/7 = 14/21
9/21 + 14/21 = 23/21 = 1 2/21
7 5/21 I think that would be the one that can cover it but not have to much left.
You might need a second opinion.
