Answer: 77/3 or 25 2/3
Step-by-step explanation:
1. Convert mixed numbers into improper fractions:
3 1/2 = 3*2+1/2 = 7/2
2 2/3 = 2*3+2/3 = 8/3
1 1/2 = 1*2+1 = 3/2
2. Calculate within parentheses
Multiply and divide from left to right
Add and subtract from left to right
Perimiter=sum of all sides
x+x-4+x-4=19
3x-8=19
add 8 both sides
3x=27
divide both sides by 3
x=9 inches
x=9 in
