Question

Jin has 34 feet of garden fence. He wants the shape of his garden to be a rectangle 5 feet wide.

Which should be the length of Jin's garden?
O A 42 feet
OB 24 feet
O c. 12 feet
D. 6 feet

Answer 1

C) 12 feet
Form equation 34=2x+10 (2 unknown lengths which are x and two 5 feet widths. They add up to his 34 feet of fence total).
Subtract 10 from both sides to whet 24=2x.
Divide both sides by 2 to isolate x and get the length is 12 feet.
