We know that rectangle EFGD has a width of 3. When we compare this 3 unit width to rectangle ABCD's width, we notice EFGC is 1/10 of ABCD. This means we are dividing by 10. ABCD's length happens to be 10. 10 divided by 10 is 1. EFGD's length is 1. Since we are solving perimeter, the expression would be 2l + 2w (w = 3, l = 1). 1 + 1 + 3 + 3 = 8 units.

Answer:

Step-by-step explanation:

So we would have to multiply the "2x - 8" by 5 each resulting in 10x - 40 + 15. Then we subtract which results in 10x - 25 = - 15. We add 25 to 25 and 15 resulting in 10x = 10. We divide each by 10 which results in x = 1.
