The perimeter is the sum of all a shapes sides.
so if length is two times the width, you could write it as 2w.
2w + 2w + w + w = 42. Simplified, it's 6w = 42.
Divide both sides by 6, and you get w = 7.
Since the length is 2w, 2 * 7 = 14, so the length is 14
Area of rectangle is length * width, so do 14 * 7 which is 98. Slap on some units and your answer is 98 sq m

x=3
Answer:
9 bracelets
Step-by-step explanation:
Divide 6/2 = 3 bracelets per hour
3 bracelets * 3 hours = 9 bracelets
9x + 26 + 7x - 17 = 2x + (-3x) + 5x =
16x + 9 = 2x - 3x + 5x =
16x + 9 = 4x
9 = 4x - 16x
9 = - 12x
-9/12 = x
- 3/4 = x
