Two step equations word problems

The perimeter of a rectangle is 34 units. Its width is 6.5 units.

1. Write an equation to determine the length (l) of the rectangle.

2. Find the length of the rectangle.

Answer 1

Equation:6.5 + 6.5 + L +L =34

Answer: 10.5

Explanation:

To find perimeter you need L+W+L+W. You have a width of 6.5. When you plug that into the equation you get 6.5 + 6.5+ L+L=34. Combine like terms (6.5 +6.5). That leaves you with 13 + 2L = 34. Now, you want to subtract 13 from both sides to isolate the L. You now have 2L = 21. Now you should divide everything by 2. 21/2 = 10.5

Answer 2

• 10.5 units

Explanation:

Given

• Perimeter P = 34 units
• Width w = 6.5 units
• Length l = ?

Equation, in terms of l:

• 2(l + 6.5) = 34
• l + 6.5 = 17
• l = 17 - 6.5
• l = 10.5
