Answer:
Width = 10 feet
Length = 2x + 4
Length = 2 (10) + 4
Length = 24 feet
Dimensions are 10 feet by 24 feet.
Step-by-step explanation:
The perimeter of a rectangle is the length of all 4 sides added together. Since it is a rectangle, we know that it has 2 pairs of identical parallel sides, so the perimeter will be 2 × the length plus 2 times the width. The problem gives us some key information so that we can solve for the dimensions. If we let x equal the width, the length will be 2x + 4 so the equation will be...
2(x) + 2 (2x + 4) = 68
2x + 4x + 8 = 68
6x + 8 = 68
6x = 60
x = 10
Since we made the width x...
Width = 10 feet
Length = 2x + 4
Length = 2 (10) + 4
Length = 24 feet
Dimensions are 10 feet by 24 feet.
